Questionnaire, Reliability Test, Teacher Competency, Validity TestAbstract
Teacher competence is the key to success in the learning process. There are several teacher competencies, including pedagogical competency, personality competency, social competency, and professional competency. Therefore, a measuring tool is needed that can measure teacher competence, one of the measuring tools that can be used is a questionnaire. This research discusses analysing question items that will be used as instruments in assessing teacher competency. Analysis of the question items was carried out by testing validity and reliability. This test aims to determine the appropriateness of the question items, as well as whether they can be trusted and relied upon to be used as instruments in a study. This research used a quantitative approach with a development method with 51 elementary school teachers as respondents in Nagari Lubuk Basung, Agam Regency. To find out whether the statement is valid or not, the corrected item's total correlation value is > 0.30. In testing the validity of this research, 38 statements were valid. It is proven that all items in the statement have a corrected item-to-total correlation value > 0.30. Measuring the reliability value of research variables uses the Cronbach's alpha value method. A construct or variable is said to be reliable if it provides a Croanbach alpha value >0.60. Based on the output in this study, the Cronbach's Alpha value for each variable was > 0.70. So that each variable is declared reliable.
