In the state of Delaware there exists a meaningful distinction between a License and a Certification, and both are used in the existing educator certification system to mean different things. Getting certified in Delaware is a two-step process, in that one must hold both a License and at least one Certificate. The License authorizes the teacher to work in a Delaware public/charter school, and the Certificate(s) identifies the area(s) in which they are authorized to teach. A Delaware educator can hold only one license type at a time depending on experience (Initial, Continuing, or Advanced); however, they can hold multiple certificates to certify their education in a specific area of expertise (Standard, Emergency, and Eligibility).
Delaware requires the prospective World Language teachers to pass a standardized assessment test to demonstrate oral and written proficiency in Mandarin Chinese, French, German, Latin and Spanish, or to achieve a minimum level of Advanced Low on the ACTFL Oral Proficiency Interview (OPI) and a passing score on ACTFL Writing Proficiency Test (WPT) (Advanced Low for languages using Roman alphabet; Intermediate High for languages using non-Roman alphabet) for other languages. For additional information about certification, please, consult the Delaware Department of Education.
