To study the effect of guidance services on students study attitude and study habits pre-test post-test control group design was used. To study the effect of guidance services on academic achievement of the students in the subjects of Biology, Mathematics, Physics, Chemistry and English. Post-test only control group design wasThere were three variables in the present study i.e. study attitudes, study habits and academic achievements in the subjects of Mathematics, Physics, Chemistry, Biology, English Text and Grammar. These variables were measured on three different types of instruments i.e. study attitude scale, study habit scale and achievement test in these subjects. Pre-test and post-test data for two variables, study attitude and study habits were available which enabled the researcher to compute the mean gain scores of both the groups on both variables. Scores on post achievement test in the five subjects were used to compare the achievement of both the groups. Independent sample t-test was run to find the significance of difference between mean achievement scores of both the experimental and the control groups. used.
