Where the grade 8 math points are

Major Content has 27 of the 55 points: exponents and scientific notation, linear equations and functions, systems, and transformations with the Pythagorean Theorem. Supporting content has 9 points, and reasoning and modeling 19. The math set has 8, 3 and 5 questions.

Grade 8 history starts in 1877

Louisiana's eighth grade course covers the United States and Louisiana from the Second Industrial Revolution to 2008: the Jim Crow era, both world wars, the Great Flood of 1927, the Cold War and the Civil Rights Movement. The social studies set follows the guide's three content categories.

  • Session 1 of grade 8 math allows no calculator, so practice exponent rules and square roots by hand.

Questions and answers

What is on the 8th grade LEAP test?

Four subjects in 2026-2027: English language arts, mathematics, science and social studies. From 2027-2028 eighth graders no longer take the science test, and the grade 8 social studies test covers grades 6 through 8.

How long is the LEAP test for 8th grade?

Math has sessions of 60, 75 and 75 minutes. English language arts has sessions of 90, 55 and 45 minutes. Science and social studies each have three sessions of 65 minutes. Every session is timed.

Can you use a calculator on the 8th grade LEAP math test?

Not in session 1. Sessions 2 and 3 allow a scientific calculator, which may not graph. Every session provides a reference sheet with volume formulas, the Pythagorean Theorem and unit conversions.

Is this the state's LEAP 8th grade practice test online?

No. The state's own grade 8 practice tests, with their answer keys, are on the department's practice tests page; the button under the questions opens it. None of its questions is used here.
