| Selection and application | Selection: There is no centralized selection. Individual NIH PIs search applications, interview candidates, choose interns and supply funding; satisfying minimum eligibility does not guarantee a match. Application materials: Personal statement; Two references who submit letters of recommendation; Outreach to NIH Principal Investigators and interviews with them | Selection: Earlier 2026 instructions described selective application followed by first-come session placement after approval. Confirm the current 2027 review and placement process; no acceptance rate is published. Application materials: Recommendation from a counselor or teacher | 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 |
