A test-retest analysis of the Vanderbilt Assessment for Leadership in Education in the USA

The Vanderbilt Assessment for Leadership in Education (VAL-ED) is a 360-degree learning-centered behaviors principal evaluation tool that includes ratings from the principal, supervisors, and teachers. The current study assesses the test-retest reliability of the VAL-ED for a sample of seven school districts as part of multiple validity and reliability assessments based on various samples of real users of the VAL-ED. We administered the VAL-ED twice and examined the correlations and mean differences between time 1 and time 2. We find that the principal and teacher ratings from time 1 and time 2 have large, positive, and significant correlations. Additionally, for both time points, principals are rated as being at least satisfactorily effective. Principals rate themselves slightly higher at time 2, while teachers rate principals slightly higher at time 1.
