The Louisiana Educational Assessment Program (LEAP) is a criterion-reference testing program administered by the state of Louisiana. It is only administered in 4th and 8th grades in the subjects of ELA, mathematics, science, and social studies. It is graded on a scale with Advanced being the highest, and Unsatisfactory being the lowest. If you are in 4th grade, it determines whether you go to the 5th grade or not. If you're in the 8th grade, it determines whether you go to the 9th grade or not.
