Reviewer 1 Report

Comments and Suggestions for Authors

Thank you for the opportunity to review this manuscript. I’d like to thank the author for an insightful piece on the implementation and effectiveness of a comprehensive public policy originally designed to serve children from zero to 6 years old in Colombia. Below I offer comments, questions, and suggestions for the author to consider as they continue to develop this manuscript. I hope the author reads my comments and suggestions in the same spirit of learning and collective knowledge creation, with which this review was written.

Introduction. I appreciate the context given regarding the historical origins and the need for the DCEO policy in Colombia. I would invite the author to expand of the environmental and sociopolitical challenges that prompted such policy and how these challenges also interfere in the implementation of the policy.

Your introduction is lacking a more clear theoretical framework. Please locate your research problem within an academic discussion and dialogue with arguments from extant literature. In other words, your manuscript is lacking a literature review of your theoretical framework. Is this piece advancing knowledge in early childhood education and development? is this a public policy piece? Is this a human rights and equity study? all of the above? Please clarify and situate your arguments within the contours of a theoretical framework.

Method. This section is extremely underdeveloped. Please provide detailed description of your corpus of analysis. How many official documents did you sample and analyze? what type of content analysis did you conduct? Qualitative? Quantitative? Rhetorical? Critical? In any case, what criteria did you use to sort and analyze your data? Please explain the medical, social, and diversity models you mentioned (these should probably be also introduced in your literature review). In short, you need to describe the steps you took to arrive to your findings and show more rigor in your methods.

Results and discussion. Please provide a preview of your findings and connect them to your research problem. Your section on Conceptual Definitions needs more depth. What is the purpose of presenting these definitions? Is the information from DANE also part of your corpus of analysis? If so, please clarify in your methods that DANE data is also part of your corpus. 

Please expand more (or add more examples) on the Care and Upbringing section. The current section does not really reflect the policy "makes a significant" effort.

There is a clear rural/urban divide in how indicators of the policy are implemented. This divide needs to be introduced in the literature review and emphasized in the findings and discussion. Further, this divide should be connected more clearly with the findings on CWDD, indigenous, and ethnic communities.

Conclusion and recommendations. Please discuss what are the theoretical implications of your study for childhood public policy. Implicate structural inequality and other systems of oppression like ableism, racism, classism, etc., in your recommendations since the failure of this policy to meet the needs of families seems to be related to larger socioeconomic structures.

I realize the volume and content of my feedback might seem overwhelming; however, your topic is relevant. I wish you the best of luck as you continue to work on this manuscript.

Comment 1: [Introduction. I appreciate the context given regarding the historical origins and the need for the DCEO policy in Colombia. I would invite the author to expand of the environmental and sociopolitical challenges that prompted such policy and how these challenges also interfere in the implementation of the policy]

Response 1: [We agree with your comment. We have included new information to expand on the socio-political challenges that made the policy possible. Throughout the text, we reflect on the progress, barriers, and challenges of the DCEO policy. Please refer to paragraphs 6 and 7 on page 2, lines 80 to 88. We also included 2 references; number 5 and 16]

Comment 2: [Your introduction is lacking a more clear theoretical framework. Please locate your research problem within an academic discussion and dialogue with arguments from extant literature. In other words, your manuscript is lacking a literature review of your theoretical framework. Is this piece advancing knowledge in early childhood education and development? is this a public policy piece? Is this a human rights and equity study? all of the above? Please clarify and situate your arguments within the contours of a theoretical framework]

Response 2: [We appreciate your comment. The introduction has been enriched with a more robust theoretical framework, which helps situate the problem and clearly define the aim of this critical review. After conceptualizing the importance of providing adequate structural and environmental conditions, we adopted the capabilities approach proposed by Nussbaum. Please refer to the new paragraphs added on page 1, paragraph 3, line 41, and page 2, paragraph 6, from lines 71 to 88. All provided information has been properly referenced; see page 11, references 36 and 37. Additionally, in consideration of the framework and the method the objective of the study was restructured, see page 3. paragraph 6, from line 11 to 116 ]

Comment 3: [Method. This section is extremely underdeveloped. Please provide detailed description of your corpus of analysis. How many official documents did you sample and analyze? what type of content analysis did you conduct? Qualitative? Quantitative? Rhetorical? Critical? In any case, what criteria did you use to sort and analyze your data? Please explain the medical, social, and diversity models you mentioned (these should probably be also introduced in your literature review). In short, you need to describe the steps you took to arrive to your findings and show more rigor in your methods.]

Response 3: [Thank you for highlighting these important methodological considerations. The method section has been revised to provide a more detailed description of the corpus analysis, the design of the review, the inclusion criteria, and the steps taken to analyze the DCAS policy. References to the medical, social, and diversity models have been removed, as the review is exclusively grounded in a human rights approach. The requested details have been incorporated into the method section on page 3, lines 117 to 144.]

Comment 4:  [Results and discussion. Please provide a preview of your findings and connect them to your research problem. Your section on Conceptual Definitions needs more depth. What is the purpose of presenting these definitions? Is the information from DANE also part of your corpus of analysis? If so, please clarify in your methods that DANE data is also part of your corpus.] 

Response 4: [We appreciate your comment, as it helped us connect the research problem with the results. Conceptual definitions are essential for identifying the approach and intentions of the DCAS policy. Following your suggestion, we included a preview to link the findings with the results, which can be seen in the first paragraph of the results section (page 3, from lines 111 to 116). Additionally, DANE is the official entity responsible for statistics, was referenced to introduce relevant data and information considered during the analysis. Furthermore, we restructured the method section on page 3, (lines 117 to 144) to clarify how this review was conducted.]

Comment 5: [ Please expand more (or add more examples) on the Care and Upbringing section. The current section does not really reflect the policy "makes a significant" effort.] 

Response 5: [Thanks for your comment. We have expanded on the Care and Upbringing section adding more examples, you can see the changes from line 208 to 2018, however, the revised information does not specify any additional details beyond those we have already included in the document.]

Comment 6: [There is a clear rural/urban divide in how indicators of the policy are implemented. This divide needs to be introduced in the literature review and emphasized in the findings and discussion. Further, this divide should be connected more clearly with the findings on CWDD, Indigenous, and ethnic communities.

Response 6: [Thank you for your comment. It has been instrumental in helping us refine the analysis of the disparities between rural and urban areas. You will find several updates in the introduction section, where we provide a clearer overview of population distribution and place greater emphasis on ethnic groups. Additionally, we have included more context regarding Colombia's socio-political situation. Please refer to page 2, paragraphs 5 and 6, for these changes. Furthermore, we have incorporated additional information to analyze how the policy impacts different populations. This can be found in the results and discussion sections, specifically in the third paragraph of page 4 and the last two paragraphs of this section on page 9.]

Comment 7: [Conclusion and recommendations. Please discuss what are the theoretical implications of your study for childhood public policy. Implicate structural inequality and other systems of oppression like ableism, racism, classism, etc., in your recommendations since the failure of this policy to meet the needs of families seems to be related to larger socioeconomic structures.

Response 7: [Following your recommendation, we have included more information in the conclusion and recommendation sections to reflect the policy’s failure to cover all children in Colombia due to structural and socio-economic barriers, which are partly a result of the historical legacy of violence. Please refer to paragraphs 1, 2, and 6 in the conclusion section and paragraphs 5 and 8 in the recommendation section.]

Reviewer 2 Report

Comments and Suggestions for Authors

A brief summary 

This paper critically examines  DCEO, a cross-sectoral policy established in Colombia in 2016 to provide coordinated and comprehensive early childhood development services. The analysis does so using a human rights lens, with a focus on conceptual components of DCEO, programming for children with disabilities, and policy effectiveness in the context of the monitoring information that is available. The findings reveal some important strengths, including the policy’s focus on equity and human dignity, while also exposing challenges around coverage in rural settings, the implementation of services for people with disabilities, and gathering systematic information on individualised interventions. The authors end with suggestions for promoting inclusivity and accessibility.

General concept comments

Overall, this is a well organised and structured manuscript, with clearly delineated sections outlining the background, methods and results. The policy analysis is well grounded and relevant literature is used to bolster the rigour of the research. Adding other key references will also make sure that it is based on existing research. As ECE continues to engage with children with different disabilities, this research is certainly part of some current conversations in the disability field. These strengths make the manuscript a useful resource to grasp the state of and move forward to improve policy frameworks.

However, they could address some issues to make this article better as outlined below. First, prioritising policy accountability mechanisms to facilitate discussion on gaps between policy design and implementation. Second, it might be useful to include a comparative analysis of early childhood policies in other Latin American countries, which would give invaluable context to the Colombian case. The manuscript should further expand on potential solutions garnered from various settings that would be applicable in addressing disparities in rural and Indigenous communities. Overall however, although the paper reports useful statistical data, it does not sufficiently explain the sources of its data, its sample sizes, or how policy evaluations were undertaken (e.g., specific methodologies of reports) monitoring).

Specific comments:

Introduction (Lines 27–79)

·       Strength: The introduction to this paper is well-written and succinct. It successfully highlights the importance of early childhood development and its lasting effects and impacts on cognitive, social, and economic outcomes. It effectively incorporates relevant international literature and policies, thereby grounding the study in established research. 

·       Concerns: Although the introduction provides a comprehensive background, it would benefit from a brief outline of the paper's structure at the end. This addition would assist readers in navigating the manuscript more easily and clarify how each section ties into the overall argument.

Methodology (Lines 80–98)

·       The study adopts a carefully structured three-phase approach, systematically analysing conceptual definitions, identifying programmes and services, and evaluating policy implementation. This structured methodology enhances the coherence of the research and facilitates a comprehensive assessment of the DCEO policy.

·       Concerns: Although the methodology is logically organised, it lacks clarity about the criteria for selecting and evaluating reports, legal documents, and policy data. The reliability and possible limitations of these sources will need to be clearly acknowledged and outlined. Since policy documents and government reports can have inherent biases, it's crucial to explain how these biases were considered in the analysis.

·       Suggestion:  The methodology section requires clear criteria for selecting official reports and legal documents, an examination of potential biases in government data and their mitigation strategies, and inclusion of alternative data sources like independent evaluations, NGO reports, and academic studies for a more balanced perspective

Conceptual Definitions (Lines 100–121)

Strengths- The DCEO policy lens is used in the manuscript to give readers a reflection of the evolving definitions of disability in policy contexts. This is a compelling example that highlights a movement forward towards a rights-based focus that includes not only gender, but also ethnicity, socioeconomic status and disability. This is in itself something laudable and shows a more nuanced view of disability in Colombia.

Concerns: There is a marked disconnect between the policy’s inclusive language and its real-life application. Although the manuscript points to this gap, this study would benefit from more engagement with the larger socio-political and economic context in Colombia. A deeper investigation into what exactly is causing this disconnect would improve the analysis substantially.

Suggestions: Discuss more about socio-political and economic factors affecting its implementation. It would also help to include a comparison table summarising important policy definitions on disability and how they compare internationally, such as against the UN Convention on the Rights of Persons with Disabilities (UNCRPD).  This approach will help clarify the alignment or divergence of the policy from global best practices.

Programs and Services for CWDD (Lines 122–196)

Strengths: The manuscript presents a systematic assessment of the different service types (education, nutrition, health, social inclusion) implemented through the DCEO policy. This section shows the spectrum of available services and provides an overview of policy approaches to addressing developmental challenges early in child development.

Concerns: While the manuscript mentions the availability of services, it does not meaningfully critique the way that effectiveness is quantified in government reports. It is not obvious whether the data elements included within the data used in official systems for monitoring whether services are accessible and impactful for children with disabilities are sufficient or adequate for determining the outcome measure of interest (i.e., inclusion) and accurately reflecting the experience of children with disabilities.

Suggestions: The author/s might need to make this part even better (1) To discuss what indicators and methodologies used in government reports in measuring the effectiveness of policies. Are they well-designed and trustworthy? Do they reflect the lived experiences of children with disabilities and their families?; and (2) Critically evaluate whether the monitoring system is focused on long-term developmental outcomes rather than a rate of service provision.

Critical Policy Evaluation (Lines 197–336)

·Strengths: The manuscript clearly outlines significant barriers to policy effectiveness, such as geographic isolation, inadequate family training, and lack of tailored support for children with disabilities. These issues are thoroughly backed by data and placed within the wider context of Colombia’s social infrastructure limitations.

Concerns: This section suffers from a significant omission of local governments, community organizations and civil society's roles in either supporting or obstructing policy execution. While the manuscript critiques central government policies, it does not sufficiently examine how decentralized governance, public-private partnerships, or community-driven initiatives could help overcome these challenges. 

Suggestions: Expand the discussion on how local governments and civil society organisations contribute to early childhood service delivery. Are there successful local initiatives that complement national policy? Consider discussing whether decentralised governance models could enhance service accessibility, particularly in rural areas. Evaluate whether public-private partnerships or NGO collaborations could help bridge existing service gaps.

These revisions would enhance the manuscript’s depth, making the policy critique more balanced and constructive.

-Suggestion:  The methodology section requires clear criteria for selecting official reports and legal documents, an examination of potential biases in government data and their mitigation strategies, and inclusion of alternative data sources like independent evaluations, NGO reports, and academic studies for a more balanced perspective

We appreciate your comment, as it highlights the need for clear criteria to define the sources used in the review to avoid potential bias. In our research, we sought to include a balanced range of materials, such as official documents—including political and legal frameworks—as well as official data and independent academic literature. The inclusion criteria for these sources are detailed on page 3, paragraph 4, line 135. Additionally, we have addressed the need for further independent research to gain a more comprehensive understanding of the policy's impact and the challenges it faces. For more details, please refer to paragraph 4 in the conclusion section on page 10, line 458.]

Response 4: [Thank you for your comment. We have followed your suggestion and made revisions to the conceptual definitions section, emphasizing the alignment of this policy with the Capabilities Approach proposed by Nussbaum (2012) and the principles established in the United Nations Convention on the Rights of Persons with Disabilities (2006). You can find these changes in the first two paragraphs of the results and discussion section, specifically in lines 148–158 and 159–169. Additionally, we have included a reference to support our analysis, see the reference section. Furthermore, we have expanded the discussion on the Colombian geographical, demographic, and socio-cultural context to provide a deeper reflection on the gaps between the policy's goals and the challenges it faces. Please refer to the third page, second paragraph, lines 105–110, as well as the reference added]

Response 6: [We appreciate your comment, as it adds valuable insight to our analysis. Indeed, a decentralized model would significantly enhance the implementation and oversight of the policy on a national scale. This idea is further elaborated on page 9, paragraph 3, specifically from lines 414 to 421.]

Reviewer 4 Report

Comments and Suggestions for Authors

The research work examines Colombian policies in relation to the special needs of the 0-5 population, which is very necessary, considering that we are talking about the most vulnerable.

Suggestions:

- Line 24: disanled children: I would used a more inclusive word; children with disabilities, children with special needs...

- Introduction: I believe that a mention to the early detection/intervention in this section would be very enriching, since in many countries it is universal and regulated by law and its benefits are evident.

- Although "developmental delay" has been used mostly, in some cases "delay" has been used (lines 75, 199, 375, 386), so it is suggested to change it to "developmental delay".

-Method section: There is important information that is not reported, which influences the transparency of the process and therefore the relevance of the results:

Who has performed the review? How many scientists?

How was the analysis performed? What tools were used? Was a qualitative software used for the anaysis? Was a categorical system created?

- Line 99: Results and Discussion.

- Results and Discussion: It is suggested that the results and discussion sections are presented in two different sections, as this may generate doubts and weaken the research work carried out.

- Lines 101-102: "... shows a progessive incorporation of the diversity..." compared to?

-Lines 110-116: It is suggested not to include anything related to implementation in the “conceptual definitions” section. Separating the results and discussion sections could solve this suggestion.

- Conclusion: It is suggested to mention information about the service providers and the lack of personnel training as they are considered of vital importance.

- It is suggested to reformulate lines 377-379, since the only way to reach those under risk conditions is screening the whole population from 0 to 5 (6) years of age.
