Just How Many Bad Teachers Does Houston Have

Ericka Mallon:

Not very many — if you believe the principals’ evaluations, which even teachers concede aren’t very good. The Houston school board heard a presentation Thursday from the New Teacher Project, and it included some fascinating data — from HISD’s own records and from surveys of teachers and principals. One slide (No. 14 below) particularly stood out: It showed that only 3.4 percent of teachers in the Houston Independent School District were rated “below expectations” or “unsatisfactory” on any domain on their appraisals between the 2005-06 school year and last school year. Looking at the domain ratings on all the evaluations from that time period, only 1 percent were below proficient.
