Liz Bowie's recent reporting on Maryland's teacher evaluation system ("About 3 percent of teachers in Md. rated ineffective," Oct. 28) raises many questions. Ms. Bowie's investigative report contains several quotes from Sandi Jacobs, the vice president of the National Council on Teacher Quality. The NCTQ is a Washington think tank with a clear political agenda that is anti-teacher and highly critical of teacher education programs across the United States. Their advisory committee includes Joel Klein and Michelle Rhee, two former school system czars who share a dislike for teachers, principals and their unions.
