WASC may grant any one of three levels of accreditation to schools: 6-year accreditation, probationary accreditation, or no accreditation.
Six-year accreditation status is a six-year term and is typically awarded when a school successfully demonstrates that it has the capacity, commitment, and competence to support high-quality student learning and ongoing school improvement. Almost all schools with a 6-year accreditation status receive a mid-term visit from a Visiting Committee at the 3-year mark.
Probationary accreditation status may be granted for either one or two years and is typically assigned to schools when there is “compelling evidence that. . .the school deviates significantly from one or more critical areas requiring immediate attention and support." Schools on probation are fully accredited and may be excellent schools in many ways; however, there is at least one area that the Visiting Committee feels cannot wait three or more years for the school to address.
WASC may withhold accreditation when "there is compelling evidence that the school does not meet one or more of the ACS WASC criteria and deviates significantly in critical areas that impact student learning and well-being, the school’s program, and supporting operations."
When an accreditation status is withheld, the school is no longer an accredited institution. This is rare, and schools will typically go through many probationary cycles without significant improvement before accreditation status is withheld.
