Pinnacle Academy

National Heritage Academies, Inc. (NHA) is a for-profit charter school management organization headquartered in Grand Rapids, Michigan. It was formed in 1995 by entrepreneur J. C. Huizenga. NHA schools use the NWEA test as a measure of student performance.

As of the 2016-17 school year, NHA operates 83 charter schools in nine states: Michigan, Indiana, Ohio, New York, North Carolina, Colorado, Georgia, Louisiana, and Wisconsin. As charter schools, NHA schools are publicly funded schools and charge no tuition. They are authorized by state-approved institutions such as universities and school boards, and therefore have no geographic boundaries. The schools focus on college preparedness and generally serve students from pre-kindergarten through eighth grade.

It is the largest charter school operator in Michigan and one of the largest charter school operators in the United States.

National Heritage Academies' stated objectives are: NHA partners with local boards to build and operate charter public schools that serve students in grades K-8.
