One-week and pre-high-school programs were capacity-based registration. Application materials: Three-week programs: online application with an essay | Selection: Local coordinators select among financially and academically eligible applicants based on performance, science interest, full-summer availability, site capacity/budget, safe commute, and mentor/project fit. ACS publishes no single current acceptance rate. |
