PJAS stands for the Pennsylvania Junior Academy of Science. Sponsored by the Pennsylvania Academy of Science, and an affiliate of the American Association for the Advancement of Science, the PJAS competition was designed to promote interest in science among junior high and senior high school students through the development of research projects and investigations. Independent science projects and the follow-up presentations are developed throughout the school year in an extracurricular fashion. Students practice application of lab skills, data analysis, science research, and presentation skills. There are now four areas to compete in a PJAS competition. These areas are Engineering, Computer Science, Mathematics, and Science. All 7th and 8th grade students are required to complete a science project and all are invited to participate in PJAS. The regional competition is usually held in February at Northampton College. For students who earn a first place award at the regional competition, an invitation is offered to compete at the state level at Penn State University in State College in May for three days. Students who receive a second place award may be invited to participate as technology support at the state level.

MathCounts is a national mathematics competition which provides engaging math programs to middle school students of all ability levels to build confidence and improve attitudes towards math and problem-solving. The program offers math enrichment while students work together building problem-solving skills through four levels of fun, engaging, and challenging math problems.  A team of students participate in a district competition in February.


Pennsylvania Mathematics League (PML) Students in grades 6, 7, and 8 are invited to participate in the PML competition. This contest is a wonderful opportunity to enrich the math curriculum and provides an academically-oriented activity for our students. Students in grade 6 typically meet after school and work together completing practice problems until taking part in the school competition. Students in grade 7 and 8 practice during class and are invited to Allentown Central Catholic High School in February to take part in the diocesan wide competition.

Scholastic Scrimmage traditionally occurs during Catholic Schools’ Week, and it highlights the academic achievements of the male and female teams from grades 5-8. Students participating in Scholastic Scrimmage are voted by their classmates to represent their grade in this scintillating academic challenge that stretches the mind and proves to be a fun, engaging competition for the entire STM school community. 


Academic Bowl is a CYO competition for 7th and 8th grade students after completing a qualifying test and trying out for the team. Weekly practices ensure strong, successful STM school representation at the annual CYO Academic Bowl challenge at Allentown Central Catholic High School. St. Thomas More school has a history of success at the CYO competition, often placing within the top three teams in the Allentown Diocese.

These opportunities are designed to keeps students engaged, foster relationships with their fellow classmates, enhance their academic experience, support the community, instill sportsmanship and collaboration, and much more. There is something for everyone to belong to and enjoy!
