A recent review of research published in the Educational Administration Quarterly reviewed 135 empirical studies that had employed the Principal Instructional Management Rating Scale (PIMRS) over the prior three decades. The author concluded that the PIMRS scale appeared to have attained a consistent record of yielding reliable and valid data on principal instructional leadership. However, given the focus of the review, little detail was provided on measurement results related to the PIMRS instrument. The current paper presents a meta-analysis of reliability results derived from 43 data sets derived from of 52 independent empirical studies in which the PIMRS had been employed for data collection. The paper verifies the strong reliability of the PIRMS.
