The Sample
Four Florida counties-namely, Alachua, Clay, Leon and Marion-were identified for this study because of their participation in the Florida Middle School Competency Project. Following the recommendation from the state department that counties design an in-service program that would provide certification for middle school teachers based on competencies, these counties devised such a plan. Teachers, then, who wished to be certified in middle school volunteered to demonstrate proficiency of a competency by using a module designed for a generic competency.
