p < .05, W1 = Spring during senior year of high school, W2 = Fall post high school, W3 = Spring post high school.

Note: For each path, there were three degrees of freedom for the chi-square difference test in model fit. The structural model was reanalyzed including race/ethnicity and SES as exogeneous covariates. The results did not change substantially and are not shown, but are available from the second author upon request.
