There are several psychology tests such as Personality,Aptitude Test, Behavioural Academic Self Esteem (BASE) and others. This research will present the hybrid approach in counselling domain using the BASE test. The system comprises of five modules, namely Student Initiative of BASE Factor 1, Social Attention of BASE Factor 2, Success / Failure of BASE Factor 3, Social Attraction of BASE Factor 4, and Self-Confidence of BASE Factor 5. By using web based application, the input was first fuzzified, then Fuzzy Associative Memory (FAM) table were constructed to handle the fuzzy rules of the five factors of BASE case study. The defuzzification technique is used to estimate the BASE factor and determine the levels of academic self-esteem such as low, moderate and high. In addition, fuzzy expert advisory provides explanation and also explain how the diagnosis is reached for a particular case.
