This study aim to develop and validate a life skills module for non-graded learners with intellectual disabilities under the k-12 transition curriculum for the School Year 20202021. This developmental research used content validation checklist and module validation checklist to validate the developed material. This study followed the Input-Process-Output (IPO) model which was viewed as a series of boxes (processing elements) connected by inputs and outputs. The study had three phases namely: Phase 1Planning on how to develop and validate life skills module; Phase 2-Developing the proposed module; and Phase 3-Validating the developed module. Based on the results, the proposed module in life skills met all the indicators or requirements needed in the module validation checklist based on the module validation made by the five experts. Moreover, the results also strongly suggest that the proposed module can be a learning material for learners with intellectual disabilities.
