Accreditation is a recognition awarded to schools that maintain a certain educational standard. The goal of the accreditation system is to ensure that a school meets acceptable levels of quality. There are two kinds of accreditation: institutional accreditation and specialized or program specialization. Accreditation organizations may evaluate the school as a whole to grant the former, while individual programs may be examined before granting the latter.
Accreditation institutions evaluate schools based on set criteria. In order to be accredited, for instance, a school may need to have a strong mission that aims to better educate its students, and prove that the mission is being achieved. Schools might also need to agree to periodic external reviews and thorough internal review programs to ensure that accreditation standards are being met. Accreditation can also be regional or national.
