Fill the Hardest Classrooms by Making the Job Hard to Get
问题
High-poverty schools couldn't attract strong graduates: the pay was low and the job carried no prestige on campus.
背景
Teach For America was founded in 1989 to address the educational inequities facing the nation's poorest communities. It recruits recent graduates, trains them intensively through a summer institute, and sends them to teach for two years in low-income schools that struggle to staff their classrooms.
Whether such fast-trained recruits could actually teach was an open, contested question. Mathematica Policy Research designed a national randomized evaluation: within each of 17 elementary schools covering grades 1 to 5, students were randomly assigned to TFA teachers or to control teachers in the same school and grade. The final sample included 100 classrooms and nearly 2,000 students.
换别人会怎么做
Raise starting pay and lower hiring bars until the seats are filled.
他们看到了什么
Scarcity, not salary, creates desire: make the unwanted position selective, branded and two years long, and ambitious graduates compete to fill seats no money could previously fill.
那一手
TFA turned staffing's hardest problem into a recruitment brand: a selective two-year 'corps' that made an underserved classroom a milestone ambitious graduates compete for, rather than a job they settle for. The district gets teachers where none would apply; the graduate gets mission, identity and peers. The randomized evaluation tested whether the brand's promise survived contact with real classrooms.
为什么管用
Selectivity converts the job's stigma into status; a defined two-year term lowers the perceived risk of committing; a corps identity supplies peers and narrative; the district buys staffing without bidding up wages.
值了多少
TFA students gained in math (effect size about 0.15) over controls in the same schools; reading showed no difference (randomized study).
什么时候会失灵
It fails where the brand outruns support: fast-trained novices without coaching can stall (reading gains here were zero); two-year turnover churns schools that need stability; and prestige fades if the corps stops being hard to get.
后来呢
The corps model, selective short-term service programs that lend prestige to understaffed missions, spread across education, health and public service; the randomized evidence became a reference point in teacher-preparation debates.
