This research aims to develop the product of the life skill education program (LSEP) which is accurate, credible, and effective. This research used the Plomp model. The model covers the input, process, output, outcome and consists of instrument, scoring guidance, and good or bad criteria. The instruments used in the model are the questionnaire, observation sheet and interview guide. The content validity of the questionnaire and observation sheet was proved by expert judgement and continued by using the Aiken Formula, the construct validity of the questionnaire was proved by the construct validity using the exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). The content validity of the questionnaire and observation sheet involved 9 validity experts. The questionnaire construct was done in two steps; the first step involved 65 students analyzed using EFA and the second step involved 199 students analyzed with CFA. The reliability of the observation sheet and questionnaire was estimated by using the Cronbach Alpha technique. The result of the trial model and its analysis shows that all the instruments are good. LSEP model is tested by involving 15 students in the course and training institute. The result of the trial model shows that the model is effective because the users explains that the model is: a) comprehensive, covering many components and sub component programs such as the input, process, output, outcome, b) practical, simple and easy in usage, c) economical, not needing much cost, energy, and time, also d) supported by valid and reliable data collection instrument.
