From The University of Central Arkansas:
Corequisite courses are planned with the intent of assisting students to be successful in college-level courses.
The Department of Student Transitions defines corequisite as two courses that are designed to be taken together in the same semester. Students are supported in their credit-bearing course by varying approaches such as: just-in-time remediation*, skills review, or coordinated curriculum. Based on certain placement guidelines from Arkansas Department of Higher Education, students are required to be enrolled in a UNIV level course. The Department of Student Transitions pairs these courses with a credit-bearing course.
*Just-in-Time Remediation. Unlike traditional multi-semester or accelerated sequential remediation models, which teach basic skills weeks or months before they are needed, “Just-in-Time” integrates these skills right before they are needed. For example, simplification of radical expressions is introduced just before the quadratic equation.
From Complete College America:
Corequisite Support: Increase gateway course completion within the first year by enrolling entering students into the college-level math and English courses, providing those who need additional help a concurrent course or lab that offers just-in-time academic support. Read more here.
From The Charles A. Dana Center:
The Power of Co-Requisites: The Dana Center strongly believes in the power of well-designed co-requisite support courses to accelerate students to success in gateway mathematics. Students are more likely to succeed in college if they earn their first college-level math credits within their first year. Read more here.
