Should we run corequisite or consecutive remediation Remediation

Should we run co-requisite or consecutive remediation?

Remediation (DE) Options • Existing Emporium Model: Remedial course then college-level course • Co. Requisite Model: Remedial course and college-level course • Which is more cost-effective from college perspective: Emporium or Co. Requisite?

Economics of Remediation Per cohort, the joint goals are to: • Maximize number passing college-level course (output) • Take fewest/cheapest number of remedial and college-level courses (costs) Co. Req (over EM): • Greater output • Higher cost (more courses + transition costs from EM) • Examine trade-off using economic model

Economic Model Parameters Calculate separately for EM and Co. Req: • DE pass rate • CL pass rate • Cost per DE course • Cost per CL course + Transition costs from EM to Co. Req

Student Flows Enrollment in Remediation 100 students Pass remedial course 80 students AND Enrollment in college-level course 60 students Enrollment in college-level course 100 students Pass college-level course 40 students Pass remedial and college-level course 80 students Total Courses Delivered = 100+60=160 Successful Students = 40 Courses per Successful Student = 4 Total Courses Delivered = 100+100=200 Successful Students = 80 Courses per Successful Student = 2. 5

Similar Cost per Course Developmental Education course College-level 3 -Credit course EM Co-Req $830 $930 $1, 000 Sources: IPEDS 2010, interviews with college personnel (1 college). Adjusted average for 13 colleges. 2015$.

Cost-Effectiveness per College: Math EM Co. Req DE students (N) 400 Success rate (r) 12. 3% 63. 3% 49 253 Total Cost (DE+CL courses + transition) $382, 100 $783, 400 Average Cost (TC/S) $7, 720 $3, 080 Yield (S=r. N)

Cost-Effectiveness per College: English EM Co. Req DE students (N) 270 Success rate (r) 30. 9% 66. 9% 83 181 Total Cost (DE+CL courses + transition) $310, 800 $524, 900 Average Cost (TC/S) $3, 750 $2, 930 Yield (S=r. N)

Conclusions • Co-Req is significantly more cost-effective than EM • But trade-off: higher cost needs much higher output • Break-even increase in output: – For Math, from 12% to 25% – For English, from 31% to 52% • All parameters may vary across each college • Cannot apply this economic model to Reading (CL course? )
