The heterogeneous nature of school refusal has led to much confusion s
urrounding the conceptualisation of this phenomenon. A number of resea
rchers have developed taxonomic systems in an effort to enhance our un
derstanding of school refusal and to facilitate communication among pr
ofessionals working in the field. The current paper explores the evolu
tion of these systems and outlines the limitations of each. Non-empiri
cal classificatory systems are reviewed first, followed by empirical s
ystems based on factor analyses and diagnostic profiles. A functional
taxonomic system for problematic school attendance is then reviewed. F
uture research based on sound methodological procedures should aim to
examine a broad range of child and family characteristics in order to
develop reliable, homogenous subtypes for this population.
