They are ill suited to identifying a student’s standing within a group or to diagnosing areas of relative strength and weakness. |\n| National Percentile Rank (NPR) | A percentile rank indicating the status or relative rank of a student's score compared with a nationally representative sample of examinees | NPRs are useful for discussing a student’s test results with parents and for determining areas of relative strength and weakness for a student, class, or grade group. They are less useful than grade equivalents, however, for estimating or monitoring growth. Do not average NPRs. |\n| Normal Curve Equivalent (NCE) | Normalized standard scores that range from 1 to 99 with a mean of 50 and a standard deviation of 21.06 in the large norm group from which they were derived | NCE scores can be interpreted in much the same way as percentile ranks, but unlike percentile ranks, NCEs CAN beaveraged when describing group performance or when checking growth over time. For these reasons, NCE scores are often used in program evaluations for reporting growth and judging improvement. |\n| Percent Correct (%C) | The result of dividing the number of questions a student answered correctly on a test by the total number of test questions and then multiplying by 100 | Do not confuse percent-correct scores with percentile ranks—the two are quite different. |\n| Percentile Rank (PR) | A score from 1 to 99 that indicates the percentage of students in a particular group that scored at or below the score of the student | PRs are especially useful for determining areas of relative strength and weakness for an individual student, a class, or a grade group. They are less useful than grade equivalents, however, for estimating or monitoring growth. Do not average PRs. |\n| Raw Score (RS) | The number of questions a student answered correctly on a test | Raw scores are usually converted to other types of scores for interpretation purposes. |\n\nContinued on next page…  \n\n| Score Type | Short Description | Use/Misuse Information |\n| --- | --- | --- |\n| Standard Score (SS) | A number that describes a student’s location on an achievement continuum with the scale based on the Iowa Assessments test subjects’ growth model | The table on page 130 shows the standard scores that correspond to typical performance (median) of grade groups on each Iowa Assessments test in the spring of the year. |\n| Stanine (S) | Normalized standard scores that range from 1 to 9 and have an average value of 5 | Stanines are coarse groupings of percentile ranks, so they are less precise indicators of student achievement than percentile ranks. Do not use stanines to describe a student’s developmental level or to measure growth. |\n\nAdditional score types and the abbreviations you may see on score reports are defined below.  \n\n| Score Type | Short Description |\n| --- | --- |\n| Grade Equivalent, 2005 Norms (AltGE) | Alternative grade-equivalent score based on 2005 norms. (Score is offered in conjunction with 2011 norms-based score.) |\n| Lexile® | A score obtained from the Iowa Assessments Reading test that can help match a student with reading material of an appropriate difficulty level. It also gives an idea of how well areader will comprehend a text. (For more information on Lexiles, see page 133.)
