"When it comes to setting the agenda for textbook publishing, only the 22 states that have a formal adoption process count...
Among the adoption states, Texas, California, and Florida have unrivaled clout. Yes, size does matter. Together, these three have roughly 13 million students in K-12 public schools. The next 18 adoption states put together have about 12.7 million...
Obviously, publishers create products specifically for the adoptions in those three key states. They then sell the same product to everybody else, because [textbooks] are very expensive to produce...
Publishers hope to recoup the costs of a big program from the sudden gush of money in a big adoption state, then turn a profit on the subsequent trickle from the "open territories." Those that fail to make the list in Texas, California, or Florida are stuck recouping costs for the next six years. Strapped for money to spend on projects for the next adoption period, they're likely to fail again. As the cycle grows vicious, they turn into lunch meat...
The big three adoption states are not equal, however. In that elite trio, Texas rules. California has more students (more than 6 million versus just over 4 million in Texas), but Texas spends just as much money (approximately $42 billion) on its public schools. More important, Texas allocates a dedicated chunk of funds specifically for textbooks. That money can't be used for anything else, and all of it must be spent in the adoption year. Furthermore, Texas has particular power when it comes to high school textbooks, since California adopts statewide only for textbooks from kindergarten though 8th grade, while the Lone Star State's adoption process applies to textbooks from kindergarten through 12th grade.
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 5 Democrats and 10 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...
Of course, publishers prefer to face no objections at all. That's why going through a major adoption, especially a Texas adoption, is like earning a professional certificate in textbook editing. Survivors just know things.
What do they know?
Mainly, they know how to censor themselves....""
