Recently, Louisiana made a change to its “cohort graduation index,” a measure used to evaluate high schools in the state, to give points to schools for students who get scores of 50 or higher on CLEP exams. From the Louisiana Department of Education (https://www.louisianabelieves.com/accountability/school-performance-scores):

School Performance Scores are based on student achievement, academic indicators and measures of career and college readiness, such Carnegie credits earned through 9th grade, graduation rates, and earning Advanced Placement, International Baccalaureate, and Dual Enrollment.

Graduation Index
Schools earn 100 points for all students graduating with a diploma. The graduation index, however, further recognizes attainment of college-credit earning scores (e.g., 3+ on an Advanced Placement exam or 4+ on an International Baccalaureate exam) and career credentials (e.g., rigorous Industry-Based Credentials). Schools may also earn points for students who earn a diploma and take an Advanced Placement test and score below 3, take an International Baccalaureate exam and score below 4, or earn credit throughTOPS-aligned dual enrollment.

According to the Louisiana Department of Education Weekly Newsletter dated October 28, 2014 (my emphasis):

The new cohort graduation index recognizes a score of 50 or higher on at least one CLEP exam as the highest level of achievement earned by a cohort graduate. Each student with at least one CLEP score of 50 or higher will earn the maximum 150 points toward the graduation index.

Local sources have told me that some schools in the state are requiring large numbers of students to take CLEP exams. This requirement is already resulting in more requests for automatic credit for first-year writing courses at the college level, and the trend will probably continue.

Currently, NCTE and CCCC do not have position statements directly addressing CLEP, though assessment for placement is a section in the following statement:

The Council of Writing Program Administrators has a Position Statement on Pre-College Credit for Writing:

though it also does not address CLEP directly.
