Look at each PSAT score report. Each section of a scored PSAT test is scored on a scale of 20 to 80 points. In 2009, the College Board reported that the average score for 10th graders in writing skills was 41, 43 in mathematics and 42 in critical reading. For 11th graders, the average scores were 46 in writing skills, 48 in mathematics and 47 in critical reading.
Look at the "Selection Index." This is the composite score of each section with a maximum of 240. This is one of the criteria used for 11th graders' eligibility in the National Merit Scholarship Program. According to the College Borad, in 2009 the reported average for the 11th grade Selection Index about 141
Compare your performance on the PSAT with the national percentile scores. This enables you to compare your performance with other U.S. students who will most likely be entering college at the same time as you. If you are in the 10th grade or lower, you will receive sophomore percentiles with your PSTA scores report. If you are in the 11th grade, you will receive junior percentiles.
