Nothing is stronger than a habit. When a habit is already established in the system or routine of an individual, it promises great, or on the opposite, damaging result to the life of that individual. The purpose of this study is to find out the relationship of study habit and Intelligence Quotient Level of high school students. Sixty high school students of Sta. Cruz, Laguna, Philippines participated in this study. It was found out that the mean level of study habit of high school students is 2.57 (frequent), the mean IQ level is 107 (average), and the mean level of academic performance is 84.12 (average). Also, it was found out that the study habit of high school students has nothing to do with their IQ level; study habit and academic performance of high school students has a low to moderate relationship, and the IQ level of high school students significantly affects their academic performance. A more frequent parent-teacher conference will play a very vital role in making the plan to create consistency. This, of course will materialize if parents have realized that they have a big part/role on their children?s achievement. Peers, parents and school should work together to improve students? performance.
