My son was administered the Woodcock Johnson tests at the end of fifth grade and again at the end of ninth grade. His scores declined in 6 out of the 9 subtests. Most notable were decreases in the Broad Written Language (down 8 points) and Written Expression (down 12 points) subtests. Is this pretty unusual? Do you have any idea of what could be going on here?
I share your concern. I do not have enough information to generalize an answer. Discuss your concerns with the professional who did the testing or with a private educational consultant.
