Study Details
Setting
The study was conducted in 52 public K-12 schools in the San Francisco Unified School District.
Study sample
Students were in grades 4 through 8. Over half (53%) were female, with 87% identified as racial/ethnic minority students, 9% identified as English language learners and 8% identified as receiving special education services. Students attended schools with an average of 59% of the students eligible for free or reduced-price lunch. Of the teacher sample, all were in their first year of teaching. The majority (78%) were female; 40% identified as a racial/ethnic minority; 86% were employed full-time; and 27%, 37%, and 37% taught primary, upper elementary, and secondary grades, respectively. .
Intervention Group
San Francisco Unified School District offers support to all novice teachers through the Beginning Teacher Support and Assessment (BTSA) program, which includes both National Board Certified Teacher (NBCT) mentors and non-NBCT mentors. BTSA mentors are matched with new teachers based on the mentor's subject expertise and geographic proximity of mentors and mentees. Teachers in the intervention condition received mentoring from mentors who were NBCTs. Mentors were expected to provide at least 1 hour of individual support per week.
Comparison Group
Teachers in the comparison condition were participating in the same BTSA program but received mentoring support from non-NBCT mentors.
Support for implementation
All mentors in the BTSA program receive training on effective ways of coaching and mentoring, goal setting for novice teachers, best practices in adult learning, individual support and reflection on mentoring practices, and ways to navigate BTSA standards and requirements.
An indicator of the effect of the intervention, the improvement index can be interpreted as the expected change in percentile rank for an average comparison group student if that student had received the intervention.
For more, please see the WWC Glossary entry for improvement index.
