Data for 1985 and on are for seniors who graduated in the year shown and had taken the ACT in their junior or senior years. Data for 2013 and on includes extended-time test takers. Possible scores on each part of the ACT range from 1 to 36.
The College Board (the developer of the SAT) and ACT, Inc. compared scores from about 600,000 students who were graduating in 2017 and who took both the SAT (2016 revision) and the ACT in 2016 and 2017. The following table shows, for each ACT composite score in the data set, the corresponding range of SAT total scores for students with the same ...
The reason for the choice of the number 21.06 is to bring about the following result: If the scores are normally distributed (i.e. they follow the "bell-shaped curve") then the normal equivalent score is 99 if the percentile rank of the raw score is 99; the normal equivalent score is 50 if the percentile rank of the raw score is 50;
Comparison of the various grading methods in a normal distribution, including: standard deviations, cumulative percentages, percentile equivalents, z-scores, T-scores. In statistics, the standard score is the number of standard deviations by which the value of a raw score (i.e., an observed value or data point) is above or below the mean value of what is being observed or measured.
Percentile ranks are commonly used to clarify the interpretation of scores on standardized tests. For the test theory, the percentile rank of a raw score is interpreted as the percentage of examinees in the norm group who scored below the score of interest. [3] [4]
Then, the raw score is converted to a scaled score. As with the other tests, a scaled score of 2100 meets the standard and 2400 is a commended performance. In 2007, the 11th grade "met standard" level was a raw score of 42, 10th was 44, and 9th was 28; 7th "met standard" with 26 points and 4th with 20. [ 10 ]
Race-norming, more formally called within-group score conversion and score adjustment strategy, is the practice of adjusting test scores to account for the race or ethnicity of the test-taker. [1] In the United States, it was first implemented by the Federal Government in 1981 with little publicity, [ 2 ] and was subsequently outlawed by the ...
There are two types of test scores: raw scores and scaled scores. A raw score is a score without any sort of adjustment or transformation, such as the simple number of questions answered correctly. A scaled score is the result of some transformation(s) applied to the raw score, such as in relative grading. The purpose of scaled scores is to ...
