In November 2018, AdvancED, which accredits schools for pre-K through grade 12 in the United States and other countries, merged with Measured Progress, which develops and supports assessment programs for schools. In August 2019, the combined organization changed its name to Cognia. The new website for the organization is https://www.cognia.org/.
The search for institutions accredited by Cognia is available here: http://www.advanc-ed.org/oasis2/u/par/search.
