Not least, a discussion of the characteristics projective techniques and the names of projective techniques commonly used in educational research.

One of the researchers work in behavioral science is to select and develop a measurement interval of the study. Research studies is dependent on the instrument used in data collection. There are a variety of tests, scales, and inventories to collect data in quantitative research, especially research dala. Researchers should be wary of the strength and limitations of available research tools to be used. They should use the tools of the best research. If the appropriate instrument was available developed by previous researchers, the better it is selected for use in research to be done. It is better than developing a new research tool. Many advantages are mainly in terms of validity, reliability and time-saving research.

The test is a set of tools for individual stimuli generate feedback commonly used score numbers. Among them is an achievement test to measure knowledge and skills in specific area and it is often used in educational research.
