It is essential in order to ensure the continuity of the learning that will be passed. Consequently, the government owing to the Language Development and Cultivation Agency has established an Indonesian Language Proficiency Test (UKBI [Uji Kemahiran Berbahasa Indonesia]), which is a standardization test for proficiency in the language of Indonesian speakers, both native and foreign speakers. Despite being a tool to measure Indonesian language skills, UKBI also has the prospect to be utilized as a medium to encourage the diversity of Indonesian cultures.
