SCORE REPORTING

SCORE REPORT INFORMATION

Passing Scores

In most instances, NLN Achievement Tests are not intended to determine pass/fail status or final grades, but to help users evaluate the effectiveness with which they are meeting the objectives of similar educational programs as defined by representatives of those programs throughout the country. The NLN does not suggest "acceptable" scores. We recommend that each program study the performance of its students in terms of the national norms and its own educational objectives.


The NLN Score Report

The score report represents the following items to aid the interpretation of test scores.

  • Test for which results are being reported, identified by name and code number
  • Identification of the type of program and the number of examinees on whose performance the norms are based
  • Testing date, specifying month/day/year on which the test was administered
  • Report date, specifying month/day/year on which the report was prepared

TYPES OF SCORES THAT MAY BE REPORTED

Raw Score

The raw score reported is generally the number of questions the student answered correctly.


Subscore

In tests with subscores, the raw scores of each part add up to the raw score of the total test, although there are a few exceptions. If the sum of the raw subscores is less than the total, it means that certain items in the test that contribute to the total score do not logically fall into any of the subscore categories reported. In those cases, a student's raw scores on the subscores may or may not add up to the total score, depending on how many of the items not classified by the subtest were correctly answered.


Percentile Score

Each percentile score indicates the percent of the norms group who received raw scores lower than the raw score the student received. For example, a student might have a total raw score of 97, with an equivalent percentile of 73. This would mean that 73 percent of the students in the norm group received raw scores less than 97 on that test.


Percentile of Subscores

Each percentile score indicates the percent of the norms group who received raw scores lower than the raw score the student received. For example, a student might have a total raw score of 97, with an equivalent percentile of 73. This would mean that 73 percent of the students in the norm group received raw scores less than 97 on that test.


Percentage Score

The percentile scores for the total test are NOT equal to the sum of the subscore percentiles, nor are they an average of the subscore percentiles. For example, it is possible for a student to obtain a total raw score at the 88th percentile on a test and obtain subscores that fall at the 86th percentile for the same norms group.

When interpreting the student’s score on a subscore, it is best to remember that the fewer items in a subscore, the larger the change in percentage score produced by a one-point change in raw score. For example, suppose a subscore includes 20 items. A single point change in the raw score will result in a change of five points in the percentage score. In a 50-item subscore, an increase or decrease of one point in the raw score will result in a change of two points in the percentage score.


Standard Score

A standard score is a transformation of the raw score earned, and expresses the distance of an individual raw score above or below the average raw score of the norms group. Where the norms group remains unchanged, standard scores are comparable from test to test, although raw scores are not.


Normalized Percentile

A normalized percentile score is the percentile equivalent (i.e., the percent of the norms group who received a raw score lower than the one in question) to a given standard score, if and only if, the scores on that test were normally distributed. The actual percentile would vary as the distribution of test scores increasingly departs from normality. Normalized percentiles sometimes appear on reports with standard scores.


Class/Group Mean

The raw score equivalent to the Class or Group Mean is obtained by averaging the raw scores of all the persons named on the report. The percentiles reported for the Class or Group Mean are those equivalent to the average raw score. (It is inappropriate to average percentiles, since the percentile of the average score is different from the average of the percentile scores).


Normalized Percentile

A normalized percentile score is the percentile equivalent (i.e., the percent of the norms group who received a raw score lower than the one in question) to a given standard score, if and only if, the scores on that test were normally distributed. The actual percentile would vary as the distribution of test scores increasingly departs from normality. Normalized percentiles sometimes appear on reports with standard scores.


Class/Group Mean

The raw score equivalent to the Class or Group Mean is obtained by averaging the raw scores of all the persons named on the report. The percentiles reported for the Class or Group Mean are those equivalent to the average raw score. (It is inappropriate to average percentiles, since the percentile of the average score is different from the average of the percentile scores).


Analysis of Responses

An analysis of the students' responses is available as of January 2013. Each content area is listed. The number of students in the class who answered the question correctly is noted beside the item number. This analysis is not provided with experimental tests. (Occasionally an item in a printed test is found to be no longer appropriate for scoring. Should this occur, examinees are not penalized for their responses to that item.)

Please Note: When you evaluate your class or conduct an individual student item analysis, use the item analysis report. This report provides a general description of the topic pertaining to the items that your class or student missed. Although you can no longer match a missed item to a specific question in the test booklet itself, concept descriptors provide sufficient direction to assist in the diagnostic use of the exam.
