New teachers who have wanted to help the city address its severe shortage of science teachers can now be considered for jobs.

Until today, the teachers had been shut out of the system because of a hiring freeze that has limited principals to teachers already working in the city. 

Principals are still limited to current teachers when they hire biology teachers, according to Department of Education spokeswoman Ann Forte. In March, there were 35 biology teachers in the “excess pool,” for teachers already on the system’s payroll, but not hired at a school. The hiring restrictions, in place since early May, were meant to make it more likely for principals to hire teachers in the pool, including those whose positions were lost to budget cuts this spring. The department still has not released information about how many teaching positions were cut this spring.

Last week, the city gave the okay to new teachers whose licenses enable them to teach in District 75, which serves the system’s most disabled students. About 70 Teaching Fellows were affected by that change.

I Teach NYC, the city’s program to attract new teachers, posted about today’s change on Twitter just after 5:30 p.m.
