Science

The National Assessment of Educational Progress (NAEP) science assessment is designed to measure students’ knowledge and abilities in the areas of Earth and space science, physical science, and life science. The most recent science assessment was given in 2024 to approximately 23,000 grade 8 students. Results for science 2024 are now available and are reported on a national level at grade 8.

Science assessment 2024

In 2024, the average science score for eighth-grade students was lower compared to 2019 and not significantly different from the average in 2009.

What Questions Are on the Test

The NAEP science framework defines content areas and levels of complexity for questions on NAEP. Using the dashboard below, explore sample questions from recent science assessments by content area and range of difficulty. Sample Questions are sourced from the NAEP Questions Tool, a database which houses over 3,000 assessment questions.

How Results Are Reported

Academic achievement in science is presented in two ways on The Nation's Report Card: scale scores and NAEP achievement levels.

  • Scale scores represent how students performed on the science assessment. Scores are aggregated and reported for diverse student groups for the nation, states, and districts.
  • NAEP achievement levels are performance standards that describe what students should know and be able to do.

Results are reported as percentages of students performing at or above three NAEP achievement levels (NAEP Basic, NAEP Proficient, and NAEP Advanced). Students performing at or above the NAEP Proficient level on NAEP assessments demonstrate solid academic performance and competency over challenging subject matter. It should be noted that the NAEP Proficient achievement level does not represent grade level proficiency as determined by other assessment standards (e.g., state or district assessments).

Item maps illustrate how specific science knowledge and skills correspond to different NAEP achievement levels. Item maps answer the question, "What does it mean for students to be at NAEP Basic, NAEP Proficient, or NAEP Advanced in terms of what they know and can do?"
