What NSPF certifications are still recognized for splash pads?
Quick answer
The National Swimming Pool Foundation (NSPF) merged with APSP in 2019 to form the Pool & Hot Tub Alliance (PHTA). NSPF-issued CPO certifications remain valid until expiration; renewals now go through PHTA. The CPO is the dominant aquatic-facility credential for splash pads.
The National Swimming Pool Foundation (NSPF) was the original issuer of the Certified Pool Operator (CPO) credential dating back to 1972. In 2019, NSPF merged with the Association of Pool and Spa Professionals (APSP) to form the Pool & Hot Tub Alliance (PHTA). NSPF-branded CPO certifications issued before the merger remain valid until their normal 5-year expiration; renewals and new certifications now go through PHTA under the same name (CPO). The course content and exam are essentially unchanged. Some older splash pad operator records still cite 'NSPF CPO,' which is the same credential as today's 'PHTA CPO' — they're equivalent. PHTA also offers Advanced Service Tech and CPI (Certified Pool Inspector) credentials. State health codes that name 'NSPF CPO' as the required certification accept the current PHTA CPO without question.
