In an effort to provide on a continuous basis information on the growth and development of Detroit's preschool students, a procedure for "Preschool Progress Reports" was implemented. The procedure requires teachers to record classroom observations of all students' skills three times during the school year on preprinted scan sheets, which are then returned to a central office for processing. Skills are measured in four major categories: social/emotional development; physical development (gross motor skills and fine motor skills); health, safety, and nutrition; and cognitive development. Schools receive two copies of progress reports for each student, one to place in his or her portfolio and one for parents. This study analyzed results from October 2001 progress reports. The study found that over 50 percent of students were rated regularly in 28 of 58 observed behaviors. A majority of students attained the highest ratings in social/emotional development, gross motor skills, and health, safety, and nutrition. Fine motor skills and cognitive development were areas in which the most students were least likely to receive the highest rating. (Appendices present data tables and figures for each of the skills.)
