The paper is based on the construction and evaluation of scientific creativity test devised for the senior secondary school students. It is an attempt that was made to evaluate validity, reliability and to determine the appropriate standards for the interpretation of the scores obtained from the scientific creativity test devised for science students. The test includes 39 items to measure three dimensions of the test which was evaluated in 220 senior secondary school students. The Content validity of the tool was evaluated by more than 20 experts and calculated by the correlation between the score of each dimension to that of the total score of the test. To decide on what items are to be retained and what to be deleted was finalized by t test for two independent samples (i.e. high group and low group based on total scores) as the questions demanded open responses. The reliability of the test has been checked by calculating Alpha Cronbach. To identify those students who are low, high and average in scientific creativities; percentile method was used to determine the adequate cutoff score for every category. The paper dealt with the steps and procedure of how the test was constructed, evaluated, and validated. Overall it was concluded that the test has good construct and discrimination validity. Moreover, all the values of reliability coefficient for each dimension are highly significant.
