Multivariate generalizability theory was applied to
the assessment of student achievement in art education.
Twenty-five art students rated the paintings of 60
fourth-grade students with regard to three criteria.
Paintings were made on four different topics. The results
indicate that generalizability is low with respect
to different raters and moderate with respect to different
topics. The three ratings a rater gave on a single
painting were moderately correlated. As indicated by
the results for the covariance components, nearly half
of the covariance between the three criteria was because
the three ratings were from the same rater. Expected
values for Q²(∆) are reported for different D
