Understanding State Reports and WinScan Interpretive Guide
North Carolina's State Summative Assessments
During the final five (5) days of a semester course or the final ten (10) days of a yearlong course, students take the staterequired EndofGrade, EndofCourse, or NCEXTEND1 assessments for the identified classes in which students are enrolled. Depending on the specific subject assessed, student scores from these assessments are used for computing school and teacher growth, proficiency rates as required by the state accountability system, and determining longterm goals and measures of interim progress designed to improve educational outcomes for all students and close achievement gaps as required under the North Carolina Every Student Succeeds Act State Plan.

EndofGrade (EOG): The EOG mathematics and reading assessments are administered to students in grades 3–8 and EOG science assessments are administered to students at grades 5 and 8 as part of the statewide program. The assessments are specifically aligned to the North Carolina Standard Course of Study (mathematics and reading) or the North Carolina Essential Standards (science) and include a variety of strategies to measure the achievement of North Carolina students.

EndofCourse (EOC): The EOC assessments are administered to students enrolled in Biology, NC Math 1, NC Math 3, and English II as part of the statewide testing program. The assessments are specifically aligned to the North Carolina Standard Course of Study (English II, NC Math 1, and NC Math 3) or the North Carolina Essential Standards (Biology) and include a variety of strategies to measure the achievement of North Carolina students.

NCEXTEND1: The NCEXTEND1 alternate assessments are for students who have a significant cognitive disability. The NCEXTEND1 is administered to eligible students as an alternate to the EOG assessments at grades 3–8 and the EOC assessments at grade 10 as part of the statewide testing program. The NCEXTEND1 assessments are specifically aligned to North Carolina's Extended Content Standards and measure the achievement of students on gradelevel extended content standards.
District administrators can produce a variety of assessment score reports on demand. Information about the most common reports (Individual Student Reports (ISRs), Achievement Level Frequency Reports, Class Roster Reports, Score Frequency Reports, and Goal Summary Reports) is intended to help educators and administrators inform decision making at the student, classroom, school, and district levels and to help explain the assessment results to parents and the general public.
Score Reports
The Individual Student Reports (ISRs) provide information to parents and educators on how students performed on state administered EndofGrade, EndofCourse, and NCEXTEND1 assessments.
Sample Class Roster Reports
Understanding the Class Roster Report
Class Roster Reports are intended for teachers and school administrators. A class roster report contains the coursespecific student scores for each content area independently or coursespecific student scores for combinations of content areas.
The Class Roster Report contains three sections: 1) the header, 2) the report body, and 3) footnotes.
Header
The first line of the header for each Class Roster Report denotes the type of assessment (EOG, EOC, or NCEXTEND1) and the school year for the test administration. The second line and/or third lines specify the assessment content or course and administration type.

Scale Score  The number of assessment questions a student answers correctly is called a raw score. The raw score is converted to a developmental scale score. 
Number Attempted  The number of questions answered by the student 
Percentile Rank  The percentile shows a student performed at a level equal to or better than the stated percentage of students who took the assessment during the standard setting year (the first year the test was administered). 
Achievement Level 
Achievement levels are predetermined performance standards that allow a student's performance to be compared to gradelevel expectations. Four achievement levels (i.e., Not Proficient, Level 3, Level 4, and Level 5) are reported for EOG and EOC tests.
Three achievement levels (i.e., Not Proficient, Level 3, and Level 4) are reported for NCEXTEND1 tests.

Class Mean  The class mean is the average of class scores. The mean is the sum of all scores in the roster divided by the number of scores in the roster.

Sample Scale Score Frequency Reports
Understanding the Scale Score Frequency Report
Frequency tables are used to summarize large quantities of scores and can be created for each EOG, EOC, and the NCEXTEND1 assessments and are intended for school level, public school unit, and state administrators.
The Scale Score Frequency Report contains three sections: 1) the header, 2) a summary table of statistics, and 3) the frequency distribution table.

Number of Students with Valid Scores  The number of student scores included in the report's group calculations and used as the denominator in calculating the mean. 
Scale Score Mean  The group mean is the average of a group of scores. The mean is the sum of all scores in the roster divided by the number of scores in the roster. 
Standard Deviation  The standard deviation indicates the degree of variation of scores among a group of students. The larger the standard deviation, the greater the variation there is in scores. The standard deviation is the square root of the variance of the scores. 
Mode 
The group mode is the most common score or scores of the group. 
High Score  The highest scale score in the reporting group 
Low Score  The lowest scale score in the reporting group 
Local Percentiles  The scale scores are listed for the 10th, 25th, 50th, 75th, and 90th percentiles. The percentile shows a student performed at a level equal to or better than the stated percentage of students who took the assessment during the standard setting year (the first year the test was administered). 
Scale Scores  The number of assessment questions a student answers correctly is called a raw score. The raw score is converted to a developmental scale score.

Percent 
The percent of students that earned a given score (number of students that earned the score divided by the total number of observations) 
Cumulative Percent  The percent of students that earned all scores up to and including the score level in the row 
Achievement Level 
Achievement levels are predetermined performance standards that allow a student's performance to be compared to gradelevel expectations. Four achievement levels (i.e., Not Proficient, Level 3, Level 4, and Level 5) are reported for EOG and EOC tests.
Three achievement levels (i.e., Not Proficient, Level 3, and Level 4) are reported for NCEXTEND1 tests.

State Percentile Rank  The percentile rank compares a student's performance on the assessment this year to that of all North Carolina students who took the assessment in the standard setting year. The percentile shows how a student performed at a level equal to or better than the stated percentage of students who took the assessment during the standard setting year. For example, if a student scores as well or better than 87 percent of the students who took the assessment in the standard setting year, the student is reported as the 87th percentile.

Sample Goal Summary Reports
Understanding the Goal Summary Report
The Goal Summary Report is a coursespecific report that summarizes student performance for content domains. The Goal Summary Report groups students at the school, district, or state level and typically reflects scores at the goal level and are intended for teachers and school, public school unit, and statelevel administrators.
The standard protocol for reporting subscale scores requires that any domain with fewer than five (5) items does not produce a level of reliability sufficient for score reporting. The Goal Summary Report provides valid data about curriculum implementation only when 1) all forms are administered within the same classroom, school, or public school unit; 2) there are at least five (5) students per form; and 3) approximately equal numbers of students have taken each form. It is best to compare a group's weighted mean percent correct with the stated weighted mean to determine how far above or below the state weighted mean the group has performed. This comparison is most appropriate because forms are comparable at a total assessment level but not the goal level. Goal Summary Reports may be available for EOG and EOC assessments; Goal Summary Reports are not provided for the NCEXTEND1 assessments due to limited item counts.
The Goal Summary Report contains three sections: 1) the header, 2) the statistics table, and 3) a footer.

Scale Score Mean 
The group mean is the average of a group of scores. The mean is the sum of all scores in the roster divided by the number of scores in the roster. 
Number of Valid Scores  Used as the denominator in calculating the mean 
Percent of Test Items  The percent of items that align with each content goal or domain 
Mean Percent Correct 
A weighted mean is used to calculate the mean scores from different forms. If the count of students differs across forms, a weighted mean adjusts for the different counts across forms. For instance, if twice as many students took one form as compared to another, this form would receive twice the weight in calculating the mean. Usually about the same number of students take each form, so in practice, the weighted mean is very similar to the unweighted mean. 
Difference State Mean Percent Correct  This difference portrays performance relative to the standard setting year state mean percent. Negative values indicate a score performance below the state mean percent correct, while positive values indicate performance above the state mean.
