This study sought to determine if the average level of student critical thi
nking at a college (i.e., the institutional context) influenced individual
students' critical thinking skills. Analyses were based on data from 23 hig
hly diverse two- and four-year institutions participating in the National S
tudy of Student Learning with controls for 15 potentially confounding influ
ences. The findings were modestly positive for students completing their fi
rst year but insignificant by the end of the third year.
