- Nationwide, eighth graders scored similarly in 1996 (148) and 2000 (149).
- In 2000, the nationwide percentage of eighth grade students performing
at or above the proficient level–identified by the National Assessment Governing
Board as the level that all students should reach–was 32 percent.
- All but seven of the participating states had averages in the basic achievement
level, indicating partial mastery; none reached a proficient or superior average.

Understanding fundamentals of science is important in modern society and a
prerequisite to further study in science or engineering. This indicator measures
the knowledge of a state's eighth grade public school students in science.
The National Assessment of Educational Progress (NAEP) is a federally authorized
ongoing assessment of student achievement. States participate at their option;
no data means the state did not participate. The assessment is based on the
NAEP Science Framework, developed through a national consensus process.
Questions cover three content areas-earth, physical, and life sciences-including
students' conceptual understanding, scientific investigation, and practical
reasoning.
The NAEP for science was administered in 1996 and 2000 to representative
samples of 4th, 8th, and 12th graders. The 2000 sample comprised 9,443 8th graders
from 385 public schools. Although the size of state samples may vary, they included
about 2,500 students from 100 schools in each state.
Student performance is described in terms of average scores on a 0–300 scale
and achievement levels: basic, proficient, and advanced.
The basic level (143–169) denotes partial mastery of the knowledge and skills
fundamental for proficient work at the eighth grade level. The proficient level
(170–207) represents solid academic performance. Students reaching this level
are competent with challenging subject matter, including knowledge, application
of such knowledge to real-world situations, and appropriate analytical skills.
The advanced level (208– 300) signifies superior performance.
