### Literature Matrix (Condensed)

| Theme | Sources For | Sources Against | Contested | Strength |
|-------|-----------|----------------|-----------|----------|
| Employer recognition improving | 8 | 3 | 2 | Moderate |
| Learner completion rates high | 6 | 4 | 1 | Contested |
| QA frameworks inadequate | 12 | 1 | 0 | Strong |
| Equity benefits | 9 | 5 | 3 | Contested |
| Skills-job alignment | 11 | 2 | 1 | Moderate-Strong |

### Synthesis Narrative

**Theme 1: Quality Assurance Frameworks Are Lagging** (Strong evidence)
The strongest finding across the literature is that existing QA frameworks were not designed for micro-credentials. Twelve of 37 sources address this theme, with near-universal agreement that current accreditation models — designed for degree programs — do not map well onto short-form, competency-based credentials (Kato et al., 2020; Wheelahan & Moodie, 2021). The European approach through the European MOOC Consortium has made progress on a common framework (Witthaus et al., 2016), but adoption remains uneven. Several authors argue that without robust QA, the micro-credential ecosystem risks becoming a "Wild West" of unverified claims (Ralston, 2021).

**Theme 2: Skills-Job Alignment Shows Promise** (Moderate-Strong)
Evidence suggests micro-credentials improve skills-job matching, particularly in technology and healthcare sectors. Employer surveys consistently report higher satisfaction with candidates who hold relevant micro-credentials alongside degrees (Brown & Kurzweil, 2023). However, alignment depends heavily on industry involvement in credential design — credentials developed without employer input show weaker labor market outcomes (Weise, 2020).

**Theme 3: Equity Outcomes Are Contested** (Contested)
The literature is split on whether micro-credentials improve or worsen educational equity. Proponents cite lower cost, flexible scheduling, and targeted skills development as benefits for underserved populations (Fishman et al., 2023). Critics counter that micro-credentials may create a two-tier system where disadvantaged learners receive "credential fragments" while privileged learners pursue full degrees (Wheelahan & Moodie, 2021). The resolution appears context-dependent: when micro-credentials are stackable toward degrees, equity benefits are stronger; when they serve as standalone alternatives, stratification risks increase.

**Theme 4: Employer Recognition Is Growing but Uneven** (Moderate)
Employer recognition of micro-credentials has increased significantly since 2020, driven partly by pandemic-accelerated digital transformation. However, recognition varies dramatically by industry, region, and credential provider. Technology sector employers show highest acceptance (78% in recent surveys), while traditional sectors like law and finance remain skeptical (under 30%) (Digital Promise, 2024).

**Theme 5: Completion and Engagement Patterns Vary** (Contested)
Completion rates for micro-credential programs range from 25% to 85% depending on program design, support structures, and learner demographics. Self-paced online formats show lowest completion (25-40%), while cohort-based blended models achieve highest rates (70-85%). Importantly, several studies note that "completion" may not be the right metric — some learners achieve their goals by completing specific modules without finishing the full credential (Reich & Ruiperez-Valiente, 2019).

### Knowledge Gaps
1. **Longitudinal outcomes**: No studies tracking micro-credential holders beyond 3 years
2. **Non-English contexts**: 89% of studies from English-speaking countries
3. **Cost-effectiveness**: No rigorous cost-benefit analyses found
4. **Stacking behavior**: Limited evidence on how learners combine micro-credentials over time

### Contradictions
| Claim A | Claim B | Assessment |
|---------|---------|-----------|
| Micro-credentials democratize access (9 sources) | Micro-credentials widen digital divide (5 sources) | Context-dependent: depends on infrastructure, digital literacy, and cost |
| High completion rates (6 sources) | Low completion for disadvantaged learners (4 sources) | Population-dependent: completion varies significantly by demographic |
