Document Number: 25711999 Trends in Academic Progress: Three Decades of Student Performance - Since 1969, the National Assessment of Educational Progress (NAEP) has conducted ongoing nationwide assessments of student achievement in various subjects. This report presents the results of NAEP's long-term trend assessments in reading, mathematics and science that were administered in 1999 to students aged 9, 13 and 17. Trends show the biggest gains occurred in mathematics achievement over the past 30 years. Some modest gains also are evident in reading. The review looks at findings from 10 administrations of the long-term trend reading and science assessments and nine administrations of the long-term trend mathematics assessment. (Jay R.
