Color touchscreen CAS graphing calculator from HP; explicitly prohibited on ACT and not included in the NCEES HP whitelist.
The HP Prime includes a computer algebra system (CAS) — the calculator category most likely to be restricted. Many university entrance tests, board exams, and competitive exams ban CAS and graphing calculators outright. Rules still vary by institution, and we have not yet verified a specific university or board policy for this model.
