. Be able to obtain a commercial driver’s license.
. Students should have mastered basic math skills. For a description of basic math, see the Basic Education section of this catalog.
. As a requirement for program entry, an Academic Skills Assessment (Compass) with appropriate benchmark scores is necessary. Program Benchmarks are Pre-Algebra: 17; Reading: 70; Writing Skills: 60. Students not meeting these benchmarks or the equivalent will be required to establish an individualized academic plan. Students may have the opportunity to enroll in selected program core courses while completing their individualized plan. Upon completion of the plan, students will be eligible for all program courses. However, higher test scores will lead to greater success in core program courses. To learn more about these assessments and program benchmark scores, please contact a counselor at (920) 498-5444 or (888) 385-6982.
