Steps of validity and Reliability of Achievement Test in Mathematics Abstract For many people, mathematics is an enigma. Characterized by the impression of numbers and calculations taught at school, it is often accompanied by feelings of rejection and disinterest, and it is believed to be strictly rational, abstract, cold and soulless. But, if the students take interest in this subject, then they can achieve better in Mathematics. In this regard the researcher has made an attempt to create the interesting learning environment through an experimental study, “Effectiveness of Teaching Mathematics with Transitional Background Music on Mathematical Achievement, Interest in learning Mathematics and Attitude towards Mathematics among secondary School Students”. In experimental studies, two kinds of information are needed. First of all, the nature of the sample and next is the measurement of desirable behavioral changes in the sample as a result of treatment variables. For collecting this information good instruments are required. Hence the researcher herself has constructed and standardized the tool that is the Mathematical Achievement Test. All the procedures followed and care was taken to assure that the tool had accepted the level of validity and reliability. Key Words: Validity, Reliability, Mathematical Achievement and Standardization.

Key Words: Validity, Reliability, Mathematical Achievement and Standardization.
