Preschool classrooms at the UBCCC include children ranging from
three to five years of age. Research shows that multi-age groupings
benefit both younger and older students in the classroom. According
to Dr. Lilian Katz, an international leader in early childhood
education, "Mixed-age grouping resembles family and neighborhood
groupings, which throughout history have informally provided much
of children's socialization and education (from The Case for
Mixed-Age Groupings in Early Education, 1990)."
