The vocational guidance process helps students in their career choices, it provides a better understanding and motivates to them to do it themselves. The lack of trained professionals to provide career guidance and the need of organized register system to help them to manage the guidance process, all this allowed the creation of Computer Assisted Career Guidance Systems (CACGS) as a part of the solution, however many of these systems have been developed for people in contexts with different characteristics as Colombian and is difficult to use their outcomes either to give guidance by counselors and to be interpreted by the students specifically from Popayan city. This paper presents a web platform designed to support vocational guidance process taking into account the students expectations on their career elections. In this research's stage the use of the intelligent web platform for vocational guidance is evaluated using a web search which includes usability metrics, and their answers help to measure the web interfaces acceptance and improve the learning process about realistic, investigative, artistic, enterprising and conventional (RIASEC) environments of the Holland's theory and how the web platform helps the students in their self-knowledge process.
