Computer Aided Learning has emerged as a significant component under SSA. The state of Tamilnadu has been proactive in providing computer facilities to schools. Most of the government schools have been provided with CAL facilities under SSA. The mission is very effective with public-private partnership in this area, both in terms of provision of software as well as teacher training. The mission, however, has concerns with the content being delivered under CAL and its impact on the teaching -learning process. Hence, the present study attempted to assess the impact of the CAL centres in terms of the students' CAL knowledge, Skills and Attitude and the secondary level teachers' attitude towards CAL. The findings present a picture that needs a multidimensional analysis. The recommendations, if implemented shall lead to effective utilization of the CAL centres both by the teachers and students, thus leading to the realization of the objectives of CAL centres under SSA.
