Understanding of SAT

Appropriate Interpretation of Its Score

• SAT assesses broadly applicable intellectual skills and knowledge that develop slowly over time through the individual’s experiences both in and out of school.

• Relationships between test scores and other factors such as educational background, gender, ethnicity, parental education, and household income are complex and interdependent. These factors do not directly affect test performance, rather, they are associated with educational experiences.

• Not all students in a high school or school district take the SAT test. Since the population of test-takers is self-selected, using aggregate SAT scores to compare or evaluate schools, districts, states, or other educational units must be very cautious.

• Interpreting SAT scores for subgroups requires unique considerations. The most significant factor to consider in interpreting SAT scores for any group, or subgroup, of test-takers is the proportion of students taking the test.

Summary

• In 2008 the total SAT (MRW) score increased 7 points from 2007, with math 5 points, critical reading and writing 1 point each.

• Among ethnic groups White made greatest progress with total score gain by 18 points, and AA made second largest progress with total score gain by 12 points.

• GCS White students have significantly outperformed NC and US White students, by all means, as measured by total (MR) score for the recent years. Our AA students performed better than NC AA students when taking participation rate into account.

• Seven high schools met tough 2008 SAT goals in all 3 subjects. Six schools outperformed NC total (MRW) mean, and 5 schools outperformed US total (MRW) mean.

• Eight students were at the top 2% nationwide. Thirty student-tests received perfect score (800).

• We should challenge our high performing students further. Most importantly we must accelerate our students with color strongly in SAT progress, especially close the gaps between White and AA students with solid measures.
