Does Louisiana test science in grade 4?
Yes. Louisiana students take LEAP 2025 Science in grade 4. LEAP 2025 tests science annually in grades 3 to 8. Grade 4 is one of Louisiana's elementary science assessment years.
Which standards does grade 4 science in Louisiana follow?
Louisiana follows the Louisiana Student Standards for Science, published by the Louisiana Department of Education. All 14 of this grade's standards are listed further down the page with their official codes.
How long are the practice tests?
Each of the six practice tests has 30 questions and a 55-minute timer. The timer auto-submits at zero and you get your score, a breakdown by science area, and a written explanation for every question.
Is any of this free?
Yes, every practice test, quiz, and flashcard set on this page is free and needs no login. Your progress is saved in your own browser and nowhere else.
What is the fastest way to use this page?
Take practice test 1 cold. Look at the topic breakdown, pick the weakest science area, and do that skill quiz. Then read the quick review for that area and come back for practice test 2.
