DVV stands for Data Validation and Verification. It is NAAC's third-party scrutiny of every quantitative metric submitted in an institution's Self Study Report (SSR). Independent reviewers cross-check the institution's claims against supporting documents (audit reports, certificates, web links, geo-tagged photos, official communications) and either accept the claim, reject it, or raise a clarification request.
Why DVV exists
Before DVV was introduced, NAAC peer teams relied largely on documents the institution itself provided during the assessment visit. This created scope for inflated or manipulated data. DVV separates data validation from on-site assessment — independent reviewers verify the numbers before the peer team sees them, ensuring assessors evaluate verified data, not institutional self-reporting.
What DVV reviewers check
DVV reviewers check every Quantitative Metric (QnM) in the SSR. For each claim, they verify: documentary evidence exists, the document supports the specific number claimed, dates align with the assessment period, signatures and authorisations are present, web links work and lead to the right page, and geo-tagged photos are dated correctly. Mismatches between the SSR claim and the evidence trigger a DVV objection.
DVV objections and clarifications
When a DVV reviewer raises an objection, the institution receives a DVV Clarification Request and a window to respond — usually 7-15 days. The IQAC must either provide additional evidence supporting the original claim or accept a revised (lower) value. Failure to respond within the window means the reviewer's revised number stands. Multiple unresolved DVV objections can drag down criterion scores significantly.
Common DVV objections
The most frequent DVV objections are: faculty publication counts unsupported by valid links or DOIs; faculty qualifications without certificates uploaded; financial figures mismatched between SSR claim and audited statement; student enrolment numbers different from AISHE/AICTE records; infrastructure facilities claimed without geo-tagged photos with proper timestamps; consultancy and funded project amounts without supporting MoUs or financial documents.
How institutions defend DVV
A strong DVV defense requires evidence-first SSR preparation — every quantitative claim is documented before it appears in the SSR, not after. Maintain a year-round criterion-wise evidence vault (most IQAC software platforms offer this). Cross-validate institutional data against external databases (AISHE, UGC, AICTE, NIRF) before submission. Train department coordinators to upload evidence as activities happen, not retroactively.
