High-capacity headmasters can certainly make improvements and create effective schools. The main purpose of this study was to report on the validity and reliability of the sustainable leadership instrument. The Sustainable Leadership Questionnaire (SLQ) instrument was used for the validity and reliability of the headmasters’ sustainable leadership practices from the teacher’s perspectives. The design of this quantitative study involved a total of 6 experts with extensive experience in the field of educational leadership to validate the content and 50 teachers from 4 indigenous primary schools in Negeri Sembilan, Malaysia who were selected using the simple random method in determining the reliability of the instrument. The analytical gains of I-CVI (0.67 to 1.00), S-CVI (0.92 to 1.00) and modified kappa statistic coefficient index (0.57 to 1.00) proved that the instrument in this study had high content validity. In line with this, Cronbach’s Alpha values, Cronbach’s Alpha if Item Deleted, Inter-Item Correlation and Corrected Item-Total Correlation were utilized to describe that the SLQ instrument in this study had good reliability. Therefore, the SLQ instrument is reliable to measure headmasters’ sustainable leadership practices from the teacher’s perspectives in the context of indigenous primary schools Malaysia. The study implied that the sustainable leadership practices of headmasters needed to be practised in schools especially in primary schools as headmasters with sustainable leadership values are highly competent and able to maintain the sustainability of schools.
