Pilot study in which supervisors rated 336 principals and 69 assistant principals in 2012/13; internal consistency was measured by Cronbach's alpha for the full FFL and each of its four categories of leadership practices. The report found "good internal consistency for both principals and assistant principals."
"Based on a pilot in which 336 principals and 69 assistant principals were rated by their supervisors in 2012/13, this interim report finds that the full FFL had good internal consistency for both principals and assistant principals."
