The 2008 Pew Center States report said that more than $1.1 billion was spent on standardized tests that year. That's just on the tests themselves. Not on implementing the tests. Any teacher can tell you that the cost of implementation is going to be even more than that because they have to hire retired teachers and subs to help with individualized education plans for special ed and small group administration. It's increasingly expensive. The Race to the Top grant program--which will likely be a blueprint for the re-authorization of the Elementary and Secondary Schools act (that's the law that NCLB came from)--requires that high-school kids take "exit" tests across all subjects. All of this money goes to a few big testing companies: Harcourt Educational Measurement, CTB McGraw-Hill, Riverside Publishing (a Houghton Mifflin company), and NCS Pearson (A UK Company).
