Evidence Base
Built on decades of peer assessment research
PeerView's methodology is grounded in a robust body of educational research spanning more than four decades. Here is the evidence.
Why peer assessment works
The case for peer-to-peer evaluation is not theoretical — it is one of the most replicated findings in educational research. When students assess each other's work through structured frameworks, both the assessor and the assessed demonstrate measurably deeper learning, stronger critical thinking, and greater retention of course material.
This body of evidence spans disciplines, institution types, and student populations. It is the foundation on which PeerView is built.
Key Findings
What the evidence shows
89%
of students report deeper engagement with course material when structured peer evaluation is used
Peer evaluation shifts students from passive recipients of feedback to active participants in the assessment process. This shift in agency is consistently associated with higher engagement scores across disciplines.

average correlation between peer grades and instructor grades — peer assessment is academically rigorous
A systematic review of peer grading studies found strong convergent validity between peer and instructor assessments when structured rubrics are used. Peer grades are not softer — they are substantively equivalent.

more feedback received per student compared to instructor-only assessment models
Volume of feedback matters. Students in peer evaluation contexts receive substantially more formative input on their work, enabling more revision cycles and deeper iterative learning.

improvement in the quality of students' own work after serving as a peer evaluator
The act of evaluating peers — reading critically, applying criteria, articulating judgment — is itself a powerful learning intervention. Students who assess others produce demonstrably stronger subsequent work.

Methodology
How PeerView operationalises the research
Structured discourse over unguided opinion
Research consistently shows that unstructured peer feedback produces low-quality, surface-level responses. PeerView's rubric-anchored evaluation framework ensures students engage with specific criteria — producing feedback that is actionable, specific, and educationally meaningful.
Calibration before evaluation
Inter-rater reliability is the central methodological challenge in peer assessment. PeerView addresses this through calibration rounds using anchor submissions — a technique validated in the assessment literature to significantly improve consistency before live evaluation begins.
Anonymity as a condition for honesty
Social dynamics suppress honest peer feedback. Anonymised evaluation — a consistent recommendation in the peer assessment literature — removes social risk and produces more candid, substantive responses. PeerView enforces anonymity by design.
AI as discourse amplifier, not substitute
PeerView uses AI tools selectively to help students articulate their thinking more precisely — expanding critical vocabulary, surfacing connections across submissions, and scaffolding richer discourse. The judgment remains the student's. The conversation remains human.
