Context & Goals• Enhanced understanding of US Community College (CC)
student success pathways
• Many initiatives to improve completion success (< 40%)• Initiatives triggered data collection / utilization• Challenges
– Heterogeneity of programs– Heterogeneity of students– Demographic & economic change– Success hard to define and to compare
• Microsimulation can complement statistical analysis

Why Microsimulation• Education research key engine in development of advanced
statistical methods, e.g. multilevel models• Individual level study progression data available• Microsimulation can complement statistical analysis
– Quantify individual level differences; decomposition– Projections accounting for composition effects– Policy analysis– Momentum point analysis– Capacity planning– Data development
• Education part of most large scale MS models; underused in education research

MicroCC: Overview• MicroCC (Micro-Community-College) is a proof of concept
model– Simple but able to reproduce observed totals, pattern
and trends– Based on real data– Output to demonstrate power and flexibility of MS
• Proved useful as demonstrational tool– Development and discussion of research proposals– Potential partners and clients – Data providers
• Used to assess data quality and needs

MicroCC: Data• Rhode Island: 2500 students per study cohort 2005+• Connecticut: 200.000 students, cohorts 2000+• Three populations:
– Rhode Island 2005– Connecticut: “Advanced Technical programs” (ATE)– Connecticut: Non-technical studies
• Variables– Demographic: age (group), sex– Race: (Non Latin) White, Black, Latin, Asian, Other– Term by term: Number of courses enrolled and passed

MicroCC: Model• Synthetic starting population sampled from the initial
distribution of students by province/program, cohort, age group, sex, race, and full-/part-time status
• Students followed over 4.5 years (9 terms)• Four decisions per term
– (Re-)enrolment decision– Fulltime / part-time decision– Number of courses enrolled (1-3; 4-10)– Courses passed
• Models estimated separately by sex and province/program: 42 logistic (& ordered logit) models
• Success: 12 courses passed (proxy for transfer-readiness)

MicroCC: Technical implementation• Implemented in the generic microsimulation language
Modgen developed and maintained at Statistics Canada
