Applying to PGSS

The 2025 PGSS program is underway and applications for the 2026 program will open in October of 2025. Please check back then for a link to apply. 

Eligibility to Apply

  1. The applicant is a rising high school senior (having completed their junior year immediately prior to the start of the program)
  2. Be a resident of the Commonwealth of Pennsylvania

Application Parts

The PGSS application consists of several parts including:
  • A personal information form
  • A summary of your science-related activities and awards
  • A summary of other activities and awards
  • A narrative essay introducing yourself and explaining why you want to participate in PGSS
  • A topical essay describing a significant influence on your interest in science or an achievement of which you are most proud
  • 2 letters of recommendation from teachers in the core subject areas of PGSS (biology, chemistry, computer science, mathematics, or physics). Each letter must be from teachers in different subject areas.
  • A letter of recommendation from your school counselor

 

 

 

Helpful Hints

In order to fully assess your scientific aptitude and potential, the PGSS application is fairly comprehensive and takes time to completely fill out. We recommend you start the process sooner rather than later!

Remember, when asking a teacher or counselor for a letter of recommendation, you should always give them 2-4 weeks notice before the application deadline. Polite reminders one week before the deadline are generally considered appropriate. 

Incomplete applications on February 1 - including those that are only missing a letter of recommendation - cannot be considered for review. It is a good idea to double check that your application has been fully submitted.
