Competency-based education (CBE) has been the dominant curriculum reform paradigm for three decades. From the European Union's key competences framework to the United States' push for outcomes-based accreditation, from medical education's milestone-based training to K-12 standards-based reforms, the basic idea—that education should be organized around what students can demonstrably do, not what they have been exposed to—has achieved near-universal policy acceptance.
Yet the gap between CBE as policy rhetoric and CBE as classroom reality remains wide. A comprehensive systematic review by Tahirsylaj and Sundberg (2025), published in The Journal of Curriculum Studies, covering research from 1997 to 2022, reveals that CBE is not one thing but at least five different things, depending on who is implementing it and why.
Five Visions of CBE
Tahirsylaj and Sundberg (2025) identify five distinct visions of how CBE has been recontextualized across different national and institutional settings:
CBE as curriculum policy discourse — competence language adopted in official documents without substantial changes to teaching practice. This is the most common form: schools and universities adopt competency frameworks on paper while classroom instruction remains largely unchanged.
CBE as curriculum policy recommendation — transnational organizations (OECD, UNESCO, EU) promoting competence frameworks as best practice, which national systems then adapt. The translation from recommendation to implementation introduces significant variation.
CBE as curriculum add-on — competencies grafted onto existing curricula as additional objectives rather than replacing traditional content organization. Teachers are asked to teach both content and competencies, often without additional time or resources.
CBE as operationalized into learning outcomes — a more systematic approach where competencies are translated into specific, measurable learning outcomes that drive assessment design. This is common in professional education, particularly medicine and engineering.
CBE as curriculum-transformative — the most radical vision, where the entire curriculum is reorganized around competency development, with content serving as a vehicle rather than an end. This vision is the rarest in practice.
The Implementation Gap
The review reveals that most CBE adoption falls into the first three categories: policy adoption without transformation. Kang, Moussavi, and Castle (2026) reach a similar conclusion in their scoping umbrella review, finding that CBE has "fragmented theoretical foundations" that create implementation and research challenges despite broad adoption. They propose a unifying meta-framework, acknowledging that the field's inconsistent theoretical approaches hinder both scalability and effectiveness.
In medical education—arguably the sector where CBE has been most systematically implemented—Emke, Torre, and Aagaard (2025) describe the "gateway experience" of successful CBE design and implementation. Their account reveals that even in a field committed to CBE, most programs have achieved only partial implementation. Full implementation requires demonstrated competence in all learning outcomes rather than average passing scores, a fundamental shift that most institutions have not completed.
<| Claim | Evidence | Verdict |
|---|---|---|
| CBE has been widely adopted globally | Tahirsylaj & Sundberg (2025): CBE reforms in nearly every national system reviewed | ✅ Supported |
| CBE consistently improves learning outcomes | Mixed — systematic reviews find inconsistent evidence | ⚠️ Inconclusive |
| CBE implementation matches policy intentions | Most adoption is superficial (discourse or add-on level) | ❌ Largely refuted |
| CBE has a unified theoretical foundation | Kang et al. (2026): fragmented foundations across disciplines | ❌ Refuted |
Where CBE Works — and Where It Struggles
Ponomariovienė, Jakavonytė-Staškuvienė, and Torterat (2025) provide evidence from primary education that personalized monitoring of student progress—a core CBE principle—can improve learning when implemented with appropriate assessment tools. Their study demonstrates that when teachers track individual competency development rather than cohort-level performance, they can identify and address learning gaps more effectively.
However, this finding highlights the resource intensity of genuine CBE. Personalized competency tracking requires assessment systems, teacher time, and institutional infrastructure that many education systems lack. The studies documenting CBE success tend to come from well-resourced settings with strong institutional commitment—conditions that are not easily replicated at scale.
CBE also faces a measurement problem. Competencies like critical thinking, collaboration, and adaptability are inherently harder to assess than content knowledge. Many CBE implementations default to assessing knowledge as a proxy for competence, which undermines the reform's fundamental premise. When competency assessment degenerates into standardized testing with competency labels, the reform becomes cosmetic.
The Assessment Challenge
Assessment is where CBE theory meets institutional reality—and where most implementations falter. Traditional assessment designs (mid-term exams, final papers, standardized tests) are misaligned with competency demonstration. Authentic competency assessment requires performance tasks, portfolios, clinical observations, or workplace evaluations—all of which are more expensive and time-consuming than conventional testing.
Medical education's experience is instructive. The entrustable professional activity (EPA) framework represents one of the most developed competency assessment models, yet even in this field, institutions struggle with observation completion rates, inter-rater reliability, and the administrative burden of comprehensive competency documentation.
Open Questions
Several important questions remain unresolved. First, does CBE actually improve the competencies it claims to develop, or does it primarily change the language used to describe traditional educational outcomes? The evidence base for improved competency development—as opposed to improved documentation of existing practices—is thin.
Second, can CBE scale to resource-constrained settings? Most success stories come from well-funded institutions with low student-to-faculty ratios. Whether CBE can be implemented effectively in large-enrollment public universities or under-resourced K-12 systems is unclear.
Third, what happens to the non-competency dimensions of education? Liberal education's goals—intellectual curiosity, aesthetic appreciation, civic identity formation—resist operationalization into competency frameworks. CBE's emphasis on measurable outcomes may inadvertently devalue these harder-to-measure educational goals.
Fourth, the labor market assumption underlying much CBE rhetoric—that employers prefer competency-credentialed graduates—lacks robust evidence. Employer hiring practices remain largely credential-based, with limited attention to competency portfolios or badge systems.
A Measured Assessment
CBE represents a reasonable response to legitimate concerns about educational relevance and accountability. The principle that education should demonstrate its outcomes is sound. But the movement has been more successful as policy rhetoric than as educational practice, and the evidence for improved learning outcomes remains inconsistent. The most promising implementations are in professional fields where competencies are well-defined and assessment is naturally performance-based. The further CBE moves from these contexts, the more its implementation challenges multiply.
