The Pennsylvania Junior Academy of Science (PJAS) is a statewide organization of Junior and Senior high school students and teachers designed to stimulate and promote interest in science through the development of research investigations. Students wishing to present their research for PJAS competition are grouped into units with other students of similar grade and category of research and evaluated by a small team of judges. Students give timed oral presentations about their projects after which judges may ask questions for a timed period. Judges score the student on their individual worksheets after each presentation. The student is rated numerically by his success in each of 5 independently-evaluated criteria. Students who achieve a first award at the regional meeting in March qualify to compete at the state meeting in May.
