There is a big boom in manpower requirements in IT industries in India in recent years. Presently India is aiming at becoming the major source of manpower in IT and other technical fields in the global scenario. To achieve this target, enhancement of employability of graduates coming out of engineering colleges are very important. A study has been conducted, which critically evaluates the educational processes and its influence on the student performance, which can be treated as a measure of employability. The study is primarily based on the accreditation data of National Board of Accreditation (NBA), India. Most of the process factors are found to be correlated with the student performance and major differences were observed between the process levels of various categories of institutes. Integration of effective teaching methodologies and necessary supporting processes in the curriculum may enhance the performance of the graduates from the engineering institutes.
