Teacher Diversity and Retention Data Note

Student Data 

The shares of students by race/ethnic group are from district level enrollment data for school year 2021-2022, available here from NYSED.  

For New York City Department of Education (NYCDOE) schools, however, we used school level enrollment data and aggregated to the geographic district, so student enrollment for District 75 schools are included in their geographic districts. This was necessary to match teacher data to student data. These enrollment files are available here from NYSED. 

Charter schools are not included in their geographic districts, but rather in a single charter district aggregated from school level enrollment data. The charter “district” and the charter Need/Resource Capacity Category (NRC) contain the same data for the same schools.   

Student data does not have a “declined” race/ethnic group.  

Teacher Data 

The shares of teachers by race/ethnic group are from a public data records request from NSYED. The data is an anonymized database extraction of full-time and part-time K-12 teachers from the 2018-19, 2019-20, 2020-21, and 2021-22 school years. It does not include substitute teachers, paraprofessionals, or after-school educators. The data may include a small fraction of the state’s prekindergarten teachers. 

The teacher retention rates are 4-year retention rates by race/ethnic group. Teachers are counted towards this retention rate if they were employed in the same district from the 2018-19 school year through the 2021-22 school year.  

Teacher data does not have a “multiracial” race/ethnic group.   

Exclusions 

We began with the 718 districts included in the 2021-22 district-level enrollment file and 330 charter schools included in the SY21-22 school-level enrollment file. We excluded 1 district and 51 charter schools that could not be matched between the teacher and student data. Our analysis includes 717 of the 718 (99.9%) districts and 279 of the 330 (85%) charter schools found in the enrollment files.
