Preschool teachers in Ohio, representing Head Start, Preschool Special Education, and Public School Preschool programs, completed a survey designed to examine their use of assessments and curricula. The 586 preschool teachers provided a range of responses, including reported use of 21 commercial assessments and self-developed and program-developed checklists. A majority of teachers listed curriculum-based measures acceptable in linking assessment and intervention. Teachers also provided a range of curricular responses, including six that met our definition of an actual curriculum. Differences were found between the three types of teachers with respect to their level of education and the total number of assessments and curricula responses, and the number of assessments (including self-developed checklists) and actual curricula used, but not years of experience.
