IATA DGR key facts & eligibility
| Conducting body | International Air Transport Association (IATA) Training — and IATA-accredited training schools / airline training centres; the regulations themselves implement ICAO Annex 18 and the ICAO Technical Instructions |
|---|---|
| Official website | iata.org ↗ |
| Mode | A function-specific dangerous goods training course (for example "DGR for Preparing DG Consignments – Initial", a 4-day / 24-hour classroom or live virtual course) followed by a stand-alone final assessment. IATA courses follow the Competency-Based Training and Assessment (CBTA) approach, and the assessment is typically worked with the DGR manual as your reference — classifying goods, selecting packing instructions and checking or completing documentation for realistic shipments. |
| Frequency | On demand, year-round — IATA schedules public classroom and virtual sessions, and accredited schools and airlines run their own courses. |
| Scoring & marking | IATA awards a Certificate of Completion to candidates who score 80% or higher on the final assessment; 90% or higher earns a certificate with distinction. |
| Score validity | The certificate is valid for 24 months. Recurrent training is mandatory within 24 months of the previous training to keep performing dangerous goods functions. |
| Language | English for most IATA sessions, with selected courses offered in French, Spanish and other languages; the DGR manual is published in several languages. |
Who is eligible for IATA DGR?
Open to anyone; IATA recommends ICAO Operational Level 4 English. The DGR requires training for everyone who prepares, offers, accepts or handles dangerous goods for air — shippers and packers, freight forwarders, cargo acceptance staff, ground handlers and loaders, passenger-handling staff and flight crew — each trained for their own function.

Expert take: what IATA DGR really tests
IATA DGR training certifies that you can apply the Dangerous Goods Regulations to the job you actually do — preparing, accepting or handling dangerous goods shipped by air. The course follows IATA's competency-based approach and ends with a final assessment needing 80% (90% earns distinction), typically worked with the DGR manual beside you. Because the DGR is republished every 1 January and certificates last 24 months, recurrent training is part of the job.
Preparation tips
- Learn to navigate the manual fast — the assessment rewards finding the right column, packing instruction and special provision, not memorising them.
- Work every shipment in the same order: classify, identify (4.2 List), check variations and special provisions, pack, mark, label, document.
- Always check whether the quantity forces Cargo Aircraft Only — and remember the CAO label and declaration box that follow.
- Read state and operator variations for the countries and airline in each scenario; the stricter rule applies.
- Practise lithium battery and dry-ice shipments specifically — they are the most common real-world DG consignments.
Common mistakes to avoid
- Using the wrong DGR edition — the manual changes every 1 January.
- Reading the passenger-aircraft columns when the package exceeds those limits and must go Cargo Aircraft Only.
- Omitting the technical name in brackets for n.o.s. entries that require it.
- Forgetting handling labels such as Cargo Aircraft Only, orientation arrows or Keep Away From Heat.
- Treating Limited Quantities as needing no Shipper's Declaration (they do; excepted quantities do not).

Best books & official prep for IATA DGR
- IATA Dangerous Goods Regulations (DGR) — current edition — IATA
- Technical Instructions for the Safe Transport of Dangerous Goods by Air (Doc 9284) — ICAO
- Emergency Response Guidance for Aircraft Incidents Involving Dangerous Goods (Doc 9481) — ICAO
Official practice: Take the IATA (or IATA-accredited) course for your job function, then practise working shipments end-to-end in the DGR: classify, find the entry in the 4.2 List of Dangerous Goods, choose the right packing instruction, and mark, label and document the package.
Previous-year papers: IATA does not publish past assessments. Course exercises and complete practice shipments are the closest equivalent.
