The instrument has a crucial function in a research. The accuracy of the data taken is also influenced by the validity of the research instrument. The validity of the research instrument will also affect the accuracy of research conclusions. Therefore, before using an instrument to retrieve data, its validity and reliability must be tested. This study tested the validity and reliability of the questionnaire instrument of the student leadership style variables.
