Abstract
The paper evaluates math performance at four high-need middle schools during a four-year intervention, which was designed to help math teachers diagnose students’ areas of need and to design lesson plans responsive to those needs. Before the intervention began, the researchers pre-selected four comparison schools by matching based on achievement and also on demographics. A difference-in-difference analysis finds a significant increase of about 0.11 standard deviation in test scores per year for students in the program schools. Supplementary event study and synthetic control analyses to detect year-by-year effects lack precision but are weakly suggestive of a smaller impact in year 1 than later years. A cost analysis considers the affordability of extending similar programs.
Acknowledgements
We are grateful to our many research partners on the Changing the Odds project including Ronald Rode, Amanda Datnow, Kimberly Samaniego, Ann Trescott, and Hayley Weddle, Leah Baylon and to our partners who implemented key parts of the reform, Kira Rua and Andrea Barraugh, for helping to make this project possible.
Ethical Approval
This research received human subjects approval from the UC San Diego Human Research Protections Program, under approval #150915SX.
Consent Form
The committee waived the requirement for informed consent from students as administrative data were used and given precautions taken to safeguard identity of students and schools, risk of breach of confidentiality was judged to be minimal.

2 In SDUSD, as in other California districts, some of the Supplemental and Concentration funding goes towards central administration needs. But countering that, SDUSD recognizes that students who meet multiple criteria, such as English Learners who are eligible for meal assistance, have greater educational needs than those who are English Learners who are not eligible for meal assistance. Therefore, the district uses duplicated counts of student needs in allocating funds to schools, which effectively increases funding to schools such as the CTO schools where many students meet two or more of the high-need criteria listed earlier.
