National Assessment of Educational Progress (NAEP)
Long-Term Trend NAEP
Long-Term Trend (LTT) NAEP was developed to measure changes in the basic achievement of students since the early 1970s. The LTT NAEP is administered in mathematics and reading to 9-, 13-, and 17-year-olds every four years. Additional information on the LTT NAEP is provided by the National Center for Education Statistics (NCES).
A comparison of all of the assessments in the NAEP program (PDF, 64KB) is available to show the differences between the assessments.
See the Main NAEP page for information on this assessment.

What's on the LTT NAEP
The LTT NAEP has remained relatively unchanged since the assessment's first administration (1971 for reading, 1973 for mathematics).
- LTT Reading features shorter passages than are found in Main NAEP and focuses on locating specific information, making inferences, and identifying the main idea of a passage. More information about what is assessed by LTT Reading is provided by NCES.
- LTT Mathematics focuses on numbers and numeration; variables and relationships; shape, size, and position; measurement; and probability and statistics. LTT NAEP assesses basic skills and recall of definitions. Students are not required to show or explain their work. More information about what is assessed by LTT Mathematics is provided by NCES.
- While not part of the content assessed, the NAEP Questionnaires for schools, teachers and students fulfill reporting requirements of federal legislation and provide a context for reporting student performance.
LTT NAEP Results
Results for LTT NAEP are usually made available anywhere from 12 to 18 months after the assessment.
