5. Review Comments to the Author

Please use the space provided to explain your answers to the questions above. You may also include additional comments for the author, including concerns about dual publication, research ethics, or publication ethics. (Please upload your review as an attachment if it exceeds 20,000 characters)

Reviewer #1: These findings contribute to our understanding of dosage for education programs offered to incarcerated individuals. The methods and analytic approach were sound. Expose to STEM courses offers an avenue of exposure I hadn't considered before. it would be interesting in the future if possible to do randomization.

Reviewer #2: Overall this paper is very well written and addresses a topic that is often overlooked. I am very pleased that the authors have conducted this research and made these data available to the public. The only aspects that I believe could have been mentioned would be the possible implications and applications of this study, i.e. have there been any studies on the effects of science learning and identity as a science learner on a prisoners' rehabilitation and re-entrance into society?
