BRSR Core assessment or assurance is annual, but the sweep does not establish an independent due-day. The mandatory tier is the top 500 listed entities for FY2025-26 and the top 1,000 for FY2026-27. The current requirement is called assessment or assurance, not assurance alone.

What changed

The earlier top-150 label is obsolete for the current sweep years. The 28 March 2025 circular also changed the terminology to assessment or assurance.

Common questions

Does the BRSR Core requirement still apply only to the top 150?

No. Top 150 was the FY2023-24 tier. The glide path covers the top 500 for FY2025-26 and the top 1,000 for FY2026-27.

Does SEBI still require assurance only?

No. The 28 March 2025 circular replaced assurance and reasonable assurance with assessment or assurance. Assessment means a third-party assessment under the Industry Standards Forum standards.
