VIDALIA — Concordia Parish students have plateaued on state tests in the last three years — neither increasing nor decreasing percentage points.

The percentage of students in the district scoring basic and above on the Louisiana Educational Assessment Program exam, or LEAP, and the Integrated Louisiana Educational Assessment Program, or iLEAP, has been 63 percent since 2011.

Statewide, 69 percent of students scored basic and above — a 1-percent increase from last year.

Students in grades four and eight took the LEAP, which are high-stakes tests that require students to achieve a certain score to proceed to the next grade.

Students in third, fourth, fifth, sixth and seventh grades took the iLEAP.

The iLEAP does not determine whether students will proceed to the next grade, but measures students’ progress.

Students taking the LEAP are required to score a basic or above on either one of their math or English exams to move on to the next grade.

Ferriday Upper Elementary School third graders showed the greatest improvement on the iLEAP in the district during April’s testing.

Third graders at the school scored 34 percentage points higher in math than last year’s third graders, with 69 percent of students scoring basic or above.

The students also scored 31 percentage points higher in science and 21 percentage points higher in English language arts.

Monterey School and Ferriday Junior High School students showed the most significant increases in the district in LEAP scores.

Eighth-grade students at Monterey scored 26 percentage points higher in science than last year’s eighth graders, with 91 percent scoring basic and above.

Eighth-grade students at Ferriday Junior High scored 29 percentage points higher in math than last year’s students, scoring 54 percent this year.

Monterey School fourth graders and Vidalia Junior High School eighth graders showed significant decreases on the LEAP test.

In Monterey, 80 percent of students scored basic and above in fourth-grade math, down 17 percentage points from last year’s students.

At Vidalia Junior High School, 67 percent of students scored basic and above in eighth grade English, down 17 percentage points from last year’s students.

Concordia Parish Superintendent Paul Nelson said Wednesday he had not yet reviewed the results of the LEAP and iLEAP state tests, which were released by the Louisiana Department of Education.

At the state level, 67 of Louisiana’s 70 school districts saw gains in the percentage of students scoring basic or above from 2011 to 2012. This is up from last year, when 48 districts achieved gains between 2010 and 2011.

Concordia Parish was ranked 46 out of the 70 school districts for percentage of students scoring basic and above on tests. The City of Monroe School District is also ranked 46.
