Through the use of the both models combination, we could obtain a comprehensive evaluation result gained from 5 evaluation components of CSE-UCLA Model such as: system assessment, program planning, program implementation, program improvement and program certification, also it was obtained accurate calculation results showed the highest down to the lowest value on any CSE-UCLA evaluation component through a calculation process using a weighted product method involving 10 evaluators in conducting a test/simulation of the method.
