In this interactive, cooperative workshop, participants will learn about achievement test administration, scoring, interpretation in light of classroom observation and other informal data, and reporting.  Participants will be encouraged to bring the assessments that they are expected to use at their schools for exploration and hands-on practice.  Instruction will include an overview of the main achievement tests (Woodcock Johnson, WIAT,KTEA), as well as more specific tests that provide useful, diagnostic information to inform instruction.
