The Credential Assembly Service (CAS) is a service provided by the Law School Admission Council (LSAC). It simplifies the law school application process by collecting and organizing applicants' academic records, letters of recommendation, and standardized test scores, such as the LSAT. Once the documents are compiled, CAS sends a complete report to the law schools chosen by the applicant. This helps streamline the admissions process, allowing schools to review candidates more efficiently and ensuring that all necessary materials are submitted in a standardized format.
