This is the seventh edition of the Brown Center Report on American Education. As in the past, the report consists of three sections. The first section examines the latest test score data on math and reading achievement. This year the analysis focuses primarily on results of the 2007 National Assessment of Educational Progress (NAEP), including a discussion of NAEP achievement levels. The second section investigates a general theme or trend in education. This year the second section scrutinizes enrollment patterns in private and public schools. Section three looks at an issue of policy relevance. International test data are examined to see whether a relationship exists between national math scores and the amount of time students spend learning mathematics in different countries. (Contains 11 tables and 41 notes.) [This report was funded by the The Brown Foundation, Inc., Houston.]
