The Raymond M. Alf Museum of Paleontology was recently reaccredited by the American Alliance of Museums.

Of the nation’s 33,000 museums, about 1,100, or 3%, are accredited. The Alf Museum is the only nationally accredited paleontology museum located on a high school campus, The Webb Schools.

“We are incredibly proud to receive reaccreditation from AAM,” said Alf Director Andrew Farke in a statement. “This recognition affirms the quality of our programs, the care and significance of our fossil collections, and our commitment to education and scientific discovery. It is also a testament to the dedication of our staff and our vibrant community of student scientists.”

The multiyear review process for reaccreditation examines a museum’s governance, collections stewardship, education, public service, financial sustainability, and “overall alignment with professional standards,” according to a news release.

The Alf contains more than 190,000 fossil specimens and facilitates student-involved field research. It was named after paleontologist Raymond M. Alf.
