This study measured the perceptions of high school advisers and MAPEH AND HOPE teachers in MANUEL ROXAS HIGH SCHOOL (MRHS) on using the Body Mass Index (BMI) and Height For Age (HFA) Autocompute, an application for School Form (SF) 8 or Learner's Basic Health And Nutrition Report in school year 2018-2019 by way of a survey conducted through the use of the BMI and HFA questionnaire, an instrument devised to evaluate the user-friendliness, clarity of the purpose, speed of computation, practicality and ease in transmitting instructions of the BMI and HFA Autocompute application to co-teachers. Noting that no standard computation and orientation were provided by the Deped to compute HFA, advisers, MAPEH leacher in the grades 7-10 and HOPE teachers for grades I1 and 12 used growth graphs taken from different websites to encode the nutritional status of students, while the
computation for BMI had been standard in all available references. After gathering responses of 30 teachers, high scores were recorded across all statements which indicated the proper
way of accomplishing SF8. The researcher traced the computation of the World Health
Organization (WHO) Child Growth Standards of 2007 for accurate interpretation of HFA, whence the HFA Autocompute was developed. The HFA Autocompute was tested accurate by
a Head Teacher and a former Coordinator both from Math Department by checking the results against WHO Growth Charts. Figures from both Growth Graphs and Autocompute were
identical. The school Registrar checked its integrity and accuracy and disseminated SF 8 with Autocompute for school year 2019-2020.

Key words:
Autocompute, BMI, HFA, School Form 8 (SF8) and Nutrition Report.
