The admissions exam for the Thomas Jefferson High School for Science & Technology received a makeover in 2017. 

According to the Fairfax County Public Schools press release, "A combination of two different tests--the ACT Aspire and the Quant Q--were selected to replace the old test. The ACT Aspire test will test reading and science skills, and the Quant Q will test math skills ... These tests replace the previous exam and will be administered on November 18."

Without any examples of the new test, we are going back to the basics. We have created our own proprietary TJ materials to focus on the concepts behind the test. In addition, we'll cover test-taking strategies to ensure that your student is ready and confident on test day.

The semifinalist round remains the same with the SIS/Essay Test. Principia's SIS/Essay classes focus on using experiences and accomplishments to demonstrate a student's fit with TJHSST. We'll approach essay questions from multiple disciplines, including math, ethics, and science-based.

Thank you for your hard work and for a great class. My student has looked forward to coming to class every weekend and is disappointed it will end. I was so glad I contacted you all after such negative experiences with other educational groups.
