DATA SNAPSHOT · 2026-08-12AJR Lifecycle 1.0

POSI Journal Lifecycle Ratings

AJR (POSI Automated Rating)is the umbrella name for the two lifecycle-specific scores below — AJR-E for early-stage journals, AJR-M for mature journals. A journal's lifecycle stage decides which track evaluates it — new journals are ranked against other new journals, established journals against other established journals, and citation impact is reported independently of both. See AJR-SPEC.md →

Track 01

Early-Stage

12–59 monthsAJR-EE-Q1–E-Q4

8 journals currently evaluated. Scored on editorial governance, research integrity, infrastructure, publishing stability, output signals, reach, and transparency.

Track 02

Mature

60+ monthsAJR-MM-Q1–M-Q4

AJR-M 1.0 methodology is implemented but has not yet been run against real evidence/citation data — no AJR-M score or M-Q has been published. Ranked separately from Citation Q.
