Why Accreditation Matters for a Ph.D. in Computer Science

Accreditation holds a lot of weight in higher education. An accredited college or program holds accountability and credibility for its educational offerings. In the U.S., recognized accrediting agencies evaluate institutions based on quality standards.

Schools can earn institutional accreditation from a national or regional accrediting agency. All legitimate accreditors will be recognized by the Council for Higher Education Accreditation and/or the Department of Education.

You should also check for programmatic accreditation when researching computer science Ph.D. programs. The best Ph.D. in computer science degrees are usually accredited by ABET.
