The purpose of this study is to develop and validate based on construct validity and sampling validity on a self-confidence scale that can measure student self-confidence at the high school level by adapting self-confidence indicators and adjusting indicators according to the character of students in Indonesia with an age range of 16-18 years. A total of 405 students from several senior high schools in Indonesia participated in this study. Respondents came from 15 schools in several regions in Indonesia. The validity test uses Pearson Product Moment which is useful for determining the validity or suitability of the instruments used by researchers in measuring and obtaining research data from respondents. While the reliability test used Alpha Cronbach the Self Confidence Scale were said to be reliable (0.794). The basis for taking the Pearson validity test is if the significance value is <0.05 then the items in the instrument are declared valid. And based on the r value of the product moment table with 405 respondents, the significance level value of 5% is more than <0.098, the result is that the instrument scale item is also said to be valid. Based on the results of the Pearson validity test, 11 self-confidence scale statement items were declared invalid or invalid because the significance level value <5% was smaller <0.098. 11 invalid statement items were declared invalid so that there were 45 items of self-confidence scale statements that were declared valid and reliable. And it can be concluded that the 45 items are declared valid and become a valid and reliable self-confidence scale and can be used to measure student self-confidence. And become instruments in a self-confidence scale that can be used to measure the level of self-confidence of high school students, especially in Indonesia.
