Louisiana Educator: The LDOE claims steady growth in student LEAP scores

Louisiana Educator: 2019 LEAP and EOC Conversion Tables

The LDOE claims steady growth in student LEAP scores

The Louisiana Department of Education recently announced the results of the Spring 2019 LEAP tests. The results statewide and by school district and school are available on the LDOE web site at links given at the bottom of the press release, here. These tables represent the LDOE's decisions on how many and what percentage of students achieved each level of achievement designated by the following categories: Unsatisfactory, Approaching Basic, Basic, Mastery, and Advanced.

The Department, in its press release, reports that Louisiana students are making steady improvement over last year on LEAP scores. This conclusion is based on the slight improvement in scale scores over last year, but since the LDOE has the authority to change the raw scores equivalent to scale scores, this conclusion is highly questionable.

The cut scores for each level of achievement may be manipulated
Each year the cut scores for each category of achievement remain the same, with the lowest passing score on LEAP tests (Basic) for grades 3-8 set at 725 points. However, the Department (LDOE) in consultation with its testing company sets the real raw scores equivalent to each level of achievement after the raw test results are in. Those raw cut scores change by a small amount each year. Some independent researchers, including myself, believe that this process allows the LDOE to manage or manipulate the reported performance of our students. Maybe that's why Louisiana's NAEP scores have dropped compared to our LEAP scores.

Scale scores are not really proportionate to the raw scores
Scale scores for each subject and grade tested run from a minimum of 650 to a maximum score of 850. If a student gets none of the answers right on a particular test she/he still gets the minimum score of 650. (This scale score seems to imply such students have actually achieved something even though they got nothing right) If the student gets all the points possible on a particular test he/she gets a score of 850. Other than those two end points, the scale score system does not tell us much about how many answers or points a student actually got right on a particular test. The actual points a student earns compared to the total possible points is called the "raw score". If we know the raw score and the total possible points on a particular test, we can calculate a raw percentage score by dividing the raw points earned by the total possible. The raw percentage score tells us how much of the material on the test a student actually got right. Unfortunately most parents never get to see their child's real raw percentage scores on state tests.
