Higher Education Accreditation is an activity that must be implemented by every college for every 5 years where this activity becomes a benchmark for college sustainability. This accreditation must be in line with the National Accreditation Agency for Higher Education (NAAHE) standards. Astra Manufacturing Polytechnic (Polman Astra) as one of the vocational higher education also conducts the accreditation. In compiling the accreditation instrument Polman Astra has a problem such as the inaccuracy of accreditation data between one department and another and the difficulty of coordinating among departments in providing data accreditation compilation. This problem may cause the late of accreditation according to a predetermined time. Due to this problem, an information system was built, namely Accreditation Information System (AIS). It is a web-based information system and designed according to NAAHE standard. AIS is built using the .NET framework and SQL Server DBMS with prototyping methodology. After implementation, AIS was able to integrate the needs of data accreditation by providing data requirements and eliminates delaying data preparation by the related department since it was directly generated from the Polman Astra database. AIS is also able to manage the accreditation data table dynamically and transparently, eliminates paper printing costs into zero and prevent delays in the preparation of accreditation instruments so that the accreditation can be completed according to a predetermined time
