The primary problem for educators and assessment researchers is reducing examiner bias and improving reliability in viva voce assessments; the primary keyword for this post is AI-assisted scoring for oral exams. According to PLOS ONE (Torab-Miandoab et al., 2026), structured oral examinations outperform traditional formats on reliability and validity, but examiner variability and logistical constraints persist. This post explains the PLOS ONE findings for qualitative researchers and assessment teams, shows where AI and qualitative methods intersect, and gives actionable steps to test AI-assisted scoring in your program.
Key Takeaways
According to PLOS ONE (Torab-Miandoab et al., 2026), a systematic review of 102 studies found structured oral exams improve reliability and fairness compared with traditional viva formats.
- From a pool of 25, 594 records screened through June 23, 2025, the review ultimately included 102 studies, according to PLOS ONE (Torab-Miandoab et al., 2026).
- According to PLOS ONE (Torab-Miandoab et al., 2026), 56.9% of included studies used structured oral examinations (SOEs), and examiner variability was reported in 66.7% of studies.
- According to PLOS ONE (Torab-Miandoab et al., 2026), technology appears in 39.2% of cases and the authors state, "Standardized oral examinations, supported by technology, offer fair and reliable assessments."
- According to PLOS ONE (Torab-Miandoab et al., 2026), reported reliability metrics included a median Cronbach's alpha of 0.75 and inter-rater ICCs ranging from 0.47 to 0.82.
What happened and how the review measured it
According to PLOS ONE (Torab-Miandoab et al., 2026), the authors conducted a PRISMA-based systematic review across 14 databases up to June 23, 2025, screening 25, 594 records to include 102 eligible studies.
According to PLOS ONE (Torab-Miandoab et al., 2026), the review coded challenges, needs, and solutions using thematic analysis and reported quantitative outcomes such as Cronbach's alpha (median 0.75) and ICC ranges (0.47–0.82).
According to PLOS ONE (Torab-Miandoab et al., 2026), common challenges were examiner-related variability (66.7%), student anxiety (41.2%), and logistical constraints (34.3%), and common solutions were examiner training (60.8%), standardization (56.9%), and technology use (27.5%).

Implications for medical educators and assessment researchers
For medical educators, the evidence in PLOS ONE (Torab-Miandoab et al., 2026) means prioritize structure, calibration, and selective technology to improve fairness and reliability.
According to PLOS ONE (Torab-Miandoab et al., 2026), programs that implemented examiner training and scoring rubrics saw inter-rater reliability improve (ICCs moving toward 0.82), so prioritize faculty calibration workshops and multi-examiner designs.
For assessment researchers, PLOS ONE (Torab-Miandoab et al., 2026) highlights research gaps: only 39.2% of studies used technology and 91.3% noted limited generalizability, so pursue multicenter validation and longitudinal studies when testing AI scoring.
How Evidano helps: from problem to AI-enabled qualitative solution
Evidano definition
Evidano is an AI-powered qualitative data analysis platform that helps researchers analyze interviews, open-ended surveys, and documents.
For teams implementing AI-assisted scoring for oral exams, Evidano provides transcription, tagged thematic analysis, and cross-segment comparisons to identify rater patterns and bias.
Problem: Examiner variability and bias
According to PLOS ONE (Torab-Miandoab et al., 2026), examiner variability accounted for a large fraction of score variance across studies, so detect and quantify rater drift early.
Solution: Evidano extracts examiner comments and rubric scores, runs thematic coding and frequency analysis, and flags systematic severity differences for calibration sessions, using features described on the Evidano features page.
Problem: Unstructured qualitative feedback
According to PLOS ONE (Torab-Miandoab et al., 2026), open-ended examiner notes and variable feedback reduce comparability across cases.
Solution: Evidano converts transcripts to coded themes, produces co-occurrence networks and word clouds, and quantifies sentiment and topic prevalence so educators can align qualitative evidence with rubric criteria.
Problem: Scaling video/audio review for fairness
According to PLOS ONE (Torab-Miandoab et al., 2026), video recording was used in 17.6% of studies to enable post-hoc review but teams reported time burdens.
Solution: Evidano supports automated transcription with custom dictionaries and PII redaction via speech-to-text, and then applies topic coding and automated summaries to reduce reviewer load while preserving audit trails.
Problem: Exploring AI-assisted scoring validity
According to PLOS ONE (Torab-Miandoab et al., 2026), the authors recommend validating AI solutions for predictive validity and bias reduction.
Solution: Evidano enables side-by-side comparison of AI-generated codes and human rubric scores, cross-segment analysis, and exportable matrices for classical psychometrics and IRT follow-up studies.
FAQ: AI-assisted scoring for oral exams
What is AI-assisted scoring for oral exams and how does it relate to qualitative research?
AI-assisted scoring for oral exams is the application of automated transcription, natural language processing, and pattern detection to support or augment human scoring.
According to PLOS ONE (Torab-Miandoab et al., 2026), the literature points to AI and NLP as promising tools to reduce rater bias and scale review when paired with structured rubrics.
Can AI reduce examiner variability in viva voce assessments?
Yes, AI can reduce examiner variability when used to standardize coding and surface rater differences for calibration.
According to PLOS ONE (Torab-Miandoab et al., 2026), interventions such as examiner training and technology-supported review improved inter-rater reliability up to ICCs of 0.82, suggesting AI can augment those interventions.
How should teams validate AI scoring for high-stakes oral exams?
Validate AI scoring by running parallel human and AI scoring, reporting reliability metrics and predictive validity, and testing for Differential Item Functioning across subgroups.
According to PLOS ONE (Torab-Miandoab et al., 2026), the authors call for multicenter and longitudinal validation studies to establish predictive validity and equity before widespread deployment.
What are the practical first steps for a qualitative researcher to pilot AI-assisted scoring?
Start with a pilot that records sessions, obtains human rubric scores, then transcribes and codes the transcripts to compare theme frequencies and examiner language.
According to PLOS ONE (Torab-Miandoab et al., 2026), video recording and post-hoc review were effective in many studies; use recorded data to iterate your rubric and train any AI models while preserving an audit trail.
How is student privacy and data security handled when using AI for oral exams?
Protect privacy by redacting PII, storing encrypted recordings, and following institutional and legal standards such as GDPR or HIPAA where applicable.
Evidano documents its data security practices on the Evidano data security page and supports PII redaction during transcription.
Conclusion & Next Steps
According to PLOS ONE (Torab-Miandoab et al., 2026), structured oral exams combined with technology and examiner calibration produce more reliable, fairer outcomes than unstructured viva formats.
For qualitative researchers and assessment teams, the practical next steps are to record a representative pilot, apply structured rubrics, and use automated transcription plus thematic analysis to identify rater patterns and content validity threats.
If you want to pilot AI-assisted qualitative analysis for oral exams, consider tools that integrate transcription, coding, and cross-segment analysis; learn more on the Evidano features page.
