Examined elementary principals' views of combination classes. Interviews indicated they preferred single-grade classes, believing that combinations led to diminished curriculum and parent and teacher concerns. They assigned effective, experienced teachers and high-ability, independent students to these classes. Few viewed combination classes as…

Queried 571 elementary school principals in 12 states to determine: (1) the frequency of nontraditional (combination and nongraded) classes; and (2) changes in the use of combination classes during recent years. Found that although combination classes represented 17% of California classrooms, most states contained only 3 to 7%. Nongraded classes…

Examined the class distributional properties of 200 elementary school classes in 2 school districts. Fifty-six classes were combination classes of students from 2 grades. Principals and teachers tended to assign higher ability and more independent students to such classes, and these assignments affected the class distributional properties.…

Describes how principals assign teachers and students to single-grade and combination classes. Presents research showing unexpected constraints that fundamentally changed the basis of class assignment and, consequently, the nature of classroom compositions. A case is made that multitrack calendars reduce principals' flexibility to make purposive…

S. Veenman argues that his reviews of the literature lead to the conclusion that combination classes are neither worse nor better than single-grade classes. This rejoinder discusses disagreements with Veenman's findings, which are hampered by a narrow reading and interpretation of the literature on potential positive effects of combination…

Research on combination classes, in which students from two or more grades are placed with one teacher for most or all of the school day, is reviewed. Consistent research findings are that combination classes, distinguished from multiage/nongraded classes, have at least a small negative effect on student achievement. (SLD)
