The Multiple Choice Tests
Some colleges provide students with a copy their Individual Score Report. If so, you will see several pieces of information for each test you completed.
Total Right Score- The total right score shows how many of the questions you could expect to answer correctly if you took a test made up of 120 questions. Any test score is an estimate.
SEM- The range tells you how accurate your score is. If you took the test a second time you could expect your new score to fall somewhere within the range shown.
Percentile Rank- The percentile rank compares your score with the scores of typical students entering college who completed tests composed of similar questions. For example, a percentile rank of 70 means that your score is higher than those of 70 percent of the students who completed the test.
Your report may also contain a list of the courses in which you may be placed. Your college will provide specific instructions about these course placements.
The Essay Tests
The score report screen will present your writing score, which will be from 1 to 6 (1 – 4 for WritePlacerÔ Texas). You will also see an explanation in writing of what your score means.
Your report may also contain information about the English course in which you may be placed. Your college will provide specific instructions about this course placement.

As Far as SEM:
What is SEM?
The standard error of measurement (SEM) is a statistical phenomenon and is unrelated to the accuracy of scoring. All test results, including scores on tests and quizzes designed by classroom teachers, are subject to the standard error of measurement.
If a student were to take the same test repeatedly, with no change in his level of knowledge and preparation, it is possible that some of the resulting scores would be slightly higher or slightly lower than the score that precisely reflects the student’s actual level of knowledge and ability. The difference between a student’s actual score and his highest or lowest hypothetical score is known as the standard error of measurement.
Because of the standard error of measurement, the potential exists that a small percentage of students may score lower than anticipated on a test, given their level of knowledge and preparation. Testing experts refer to this phenomenon as a “false negative.” False Positive
Conversely, the possibility exists that a small percentage of students may score higher than otherwise would have been expected. Testing experts refer to this phenomenon as a “false positive.”
Hope it helps it also depends on what state you took the test in as to how SEM is looked at if at all!!
