CABO · Certification Levels
Four tiers.
Progressive maturity.
CABO certification recognises operators along a four-tier maturity scale. Tiers are not labels — they are evidenced thresholds across all four G-O-E-A pillars.
Why Tiered Certification
Certification is a pathway, not a pass/fail.
Public transport operators across Africa start from very different operational baselines. A single pass/fail certification forces large, mature operators and emerging operators into the same category. CABO's four-tier structure recognises progress, sets visible targets, and allows operators to work toward certification one level at a time.
The Four Levels
Foundation to Leading.
Foundation
Baseline operational control established.
The operator has established the minimum governance, operating, and evidence structures required for a recognisable operational discipline to exist.
Headline Criteria
-
Governance charter and decision rights documented
-
Core SOPs and timetables in place and maintained
-
Dispatch & depot readiness routines operating
-
Basic performance reporting and incident logs
Established
Operational discipline working end-to-end.
All four pillars are active and connected — service design feeds execution, execution produces evidence, and governance acts on that evidence.
Headline Criteria
-
All four G-O-E-A pillars active with evidence
-
OTP, incident, and resource KPIs tracked monthly
-
Internal audit cycle running at least annually
-
Formal response loops closing material incidents
Advanced
Integrated, data-driven operations.
Operations run on structured data and proactive control. Certification evidence is maintained continuously, not rebuilt for each audit.
Headline Criteria
-
Real-time operational dashboards in daily use
-
Evidence portfolio maintained continuously
-
Quarterly surveillance audits with closed remediation
-
Service change management fully controlled
Leading
Reference-grade operator.
Operational performance is at the level the CABO framework exists to promote. The operator can demonstrate sustained performance across all pillars and serves as a reference for peer operators.
Headline Criteria
-
Consistently meets certification thresholds across all pillars
-
Independent oversight with continuous improvement
-
Publishes structured operational performance
-
Supports peer operators through knowledge transfer
Progression Pathway
How operators move up the tiers.
Progression is evidence-driven. Each tier demands demonstrable, sustained performance across all four G-O-E-A pillars — not just strength in one or two.
Entry Point
Operators can enter certification at any tier — the baseline assessment places the operator at the correct starting point.
Re-Certification
Each tier has a defined validity period. Re-certification tests that performance has been sustained, not improved for audit.
Progression Cadence
Moving up a tier typically requires 12–24 months of evidenced performance at the next level's thresholds.
