If you're creating a new textbook, therefore, you start by scrutinizing "Texas Essential Knowledge and Skills" (TEKS). This document is drawn up by a group of curriculum experts, teachers, and political insiders appointed by the 15 members of the Texas Board of Education, currently five Democrats and ten Republicans, about half of whom have a background in education. TEKS describes what Texas wants and what the entire nation will therefore get.
Texas is truly the tail that wags the dog. There is, however, a tail that wags this mighty tail. Every adoption state allows private citizens to review textbooks and raise objections. Publishers must respond to these objections at open hearings.
