38 CFR 21.124 - Combination course.
(a) General. A combination course is a course which combines training on the job with training in school. For the purpose of VA vocational rehabilitation, a course will be considered to be a combination course, if the student spends full-time on the job and one or more times a week also attends school on a part-tme basis. A veteran may pursue the components of a combination course in the following manner:
(1) Concurrent school and on-job training;
(2) Primarily on-job with some related instruction in school;
(3) In a school as a preparatory course to entering on-job training; or
(4) First training on-job followed by the school portion.
(b) Cooperative course. A cooperative course is a special type of combination course which usually:
(1) Has an objective which the student attains primarily through school instruction with the on-job portion being supplemental to the school course;
(2) Is at the college or junior college level although some cooperative courses are offered at post-secondary schools which do not offer a college degree or at secondary schools;
(3) Requires the student to devote at least one-half of the total training period to the school portion of the course; and
(4) Includes relatively long periods each of training on the job and in school such as a full term in school followed by a full term on the job.
