This analysis was conducted to examine the relationship between Wake Count Public Schools' students' performance on mid-year benchmark assessments and End-of-Grade (EOG) tests in both reading and math in grades 3-5 in school year 2010-11. Strong positive correlations were found between the mid-year benchmark assessment and EOG test scores for each subject and grade level. A linear regression analysis showed that benchmark assessment scores can predict EOG scores while accounting for about two-thirds of the variation in EOG scores for math and over half of the variation in EOG scores for reading. Results showed that the benchmark assessments given mid-year can provide valuable information about which students are likely to do well on the EOG test and which may need extra support. The following appendices are included: (1) Percent of Students at Each EOG Achievement Level within Benchmark Results Range in Mathematics; and (2) Percent of Students at Each EOG Achievement Level within Benchmark Results Range in Reading.
