Curriculum mapping can be used to visualize, align, and assess the ability of online degree program graduates to meet stated learning outcomes (Rawle et al., 2017). Though consensus has yet to be established on standardized outcomes for curriculum in some disciplines (e.g., criminal justice), educators remain in charge of preparing current and future practitioners for success. We know measuring student performance is the norm, but a standardized vision of the outcomes being analyzed has yet to be realized. Regardless of the specific outcomes a degree program prepares students for, it seems reasonable that the outcomes would be measured and evaluated by educators and administrators to improve student performance over time. Unfortunately, no standardized recipe for that success exists, especially as instructional delivery shift to online environments and student demographics change. Some disciplines need more consensus on what qualities (outcomes) are most important for career success. However, once established, the question remains of adequately assessing those outcomes and driving student performance positively. As administrators, we hope our students achieve measurable outcomes to prepare them for their chosen career fields. The question thus remains: How do we ensure the course curriculum adequately addresses stated program outcomes? Internal assessment tools are often used, but this method may not always be enough. The answer may lie with external benchmarking or a similar form of summative assessment, at least during initial curriculum validation. Regardless of the chosen validation strategy, student achievement against those outcomes should be measured. Summative assessment has proven helpful in benchmarking student performance against learning objectives, though assessments are often only internal, leaving a need for external validation. While the author agrees that learning objectives should be established, an argument is not made about which objectives are most important for criminal justice majors, as is used in the present study. Instead, this research provides a potential framework for improving student performance in meeting program outcomes using an externally validated benchmarking approach for online adult learners in a criminal justice bachelor's program. Specifically, this research aims to show how external benchmarking was used to revise course curriculum mapping and improve student outcome achievement in an online undergraduate criminal justice program.
