The document describes the Learner Information System (LIS) used by Buhatan National High School. The LIS aims to standardize learner registration, track learner performance and progress, provide information for planning, and manage learner records. Classroom advisers are responsible for enrolling learners accurately in the system and updating learner data. Guidelines specify that annual enrollment data should be entered by July 11th and include learners attending from the school opening until the first Friday cutoff date. Late enrollees and additional tags for programs should also be recorded.
