| Selection and application | Selection: Applicants must persuade Euler Circle that they are prepared and a good instructional fit; Euler Circle says ordinary seat scarcity usually is not the main constraint and does not publish acceptance statistics. | Selection: The 2026 cohort reached capacity and accepted waitlist interest. Scholarships were limited and considered merit and need. Current cohort size, applicant count, acceptance rate, selection rubric, and waitlist movement are not published. | Selection: PGSS describes a statewide application and admission process but the current official pages publish neither cohort size, applicant count nor acceptance rate. Application materials: Narrative essay introducing yourself and why you want to attend PGSS; Topical essay on a significant influence on your interest in science or an achievement; Two teacher recommendations from different PGSS core subjects; School counselor recommendation |
