The purpose of this research was to develop the Caring School Leadership Questionnaire (CSLQ) as a valid and reliableinstrument to measure the extent of care being given by school leaders (principals) to teachers. The research involved 1,041teachers and 65 principals from 68 primary schools in the North-West Province of South Africa. The construct validity ofthe CSLQ was determined by means of a confirmatory factor analysis. The three main constructs regarding caring thatemerged from the factor analysis proved to be the same as those theoretically identified as the three main determinants ofcare. Cronbach’s Alpha coefficients furthermore proved the CSLQ to be reliable. The key finding flowing from theinvestigation was that the CSLQ may be applied with good effect in 180º-, 360º-, as well as self-evaluations of school leaders.Keywords: caring, caring school leadership, determinants of care, management, measuring instrument for caring schoolleadership, measuring care in leadershi
