Teach advanced open-circuit normoxic trimix decompression diving with confidence and precision.
Begin your transition to RAID’s global instructor framework.
The RAID Normoxic Decompression Instructor rating authorises you to teach and certify divers conducting open-circuit normoxic trimix decompression dives to 60 metres / 200 feet, in accordance with RAID technical standards.
This rating represents the transition from advanced air and limited trimix instruction into full normoxic trimix decompression training, where gas density management, END control, and staged decompression precision become critical instructional responsibilities.
As a RAID Normoxic Decompression Instructor, you are authorised to teach and certify:
RAID Normoxic Decompression Diver (60m)
Advanced open-circuit decompression programs using normoxic trimix
Multi-gas decompression profiles within RAID limits
You act as the instructional gatekeeper for divers entering deeper mixed-gas open-circuit environments.
This instructor development program focuses on instructional leadership, supervision, and evaluation, rather than personal depth progression.
You will refine your ability to:
Teach normoxic trimix theory and gas selection
Instruct staged decompression planning and execution
Manage PO₂ exposure and END limits
Teach gas switching protocols and discipline
Evaluate student dive plans and decompression strategies
Apply RAID assessment criteria accurately
You will be evaluated on your ability to:
Demonstrate all open-circuit skills neutrally buoyant and in trim
Maintain precise buoyancy and situational awareness
Supervise multi-gas ascents and decompression stops
Control student positioning during gas switches
Intervene effectively during failures or stress events
Maintain oversight across multiple students
You will develop:
Advanced risk management strategies
Clear instructional command presence underwater
Conservative decision-making under task loading
Professional judgement in complex decompression environments
Instructor Level: Leadership / Technical Open Circuit
Gas Scope: Normoxic Trimix
Maximum Teaching Depth: 60m / 200ft
Teaching Environment: Staged decompression, multi-gas OC diving
Evaluation Standard: Demonstration-quality skills
Instructor Oversight: RAID Instructor Trainer
Certification Type: Open-circuit (non-CCR)

To enrol in this course, candidates must:
Hold RAID Advanced Decompression Instructor or equivalent
Be certified as a RAID Normoxic Decompression Diver
Maintain current RAID professional registration
Hold valid First Aid, CPR, and Oxygen Administration
Meet RAID medical and administrative requirements
Demonstrate sufficient open-circuit decompression experience as required by RAID
All prerequisites are verified during the instructor application process.
Instructor development follows a structured, three-stage progression, aligned with RAID leadership standards.
You will complete leadership-level academics covering:
RAID Normoxic Decompression standards and limits
Instructor responsibilities and liability
Student supervision and positioning strategies
Risk management for staged decompression
Multi-gas planning and verification
Teaching methodology and evaluation criteria
You will demonstrate:
S-Drill and gas donation protocols
Buoyancy and trim control under task load
Gas switch procedures and verification
Decompression stop discipline
Valve shutdowns (where applicable)
SMB deployment while hovering
Lost mask and failure management drills
All skills must be completed neutrally buoyant and assessed against RAID criteria.
Your evaluation focuses on your ability to:
Supervise Normoxic Decompression training dives
Maintain instructor positioning and situational awareness
Control student behaviour during ascents and gas switches
Manage decompression failures and contingencies
Evaluate student performance objectively
Demonstrate calm, authoritative leadership
Instant access to your online learning, course preparation modules. Begin training immediately.

Once certified, you will be authorised to:
Teach RAID Normoxic Decompression Diver programs
Supervise staged decompression dives using normoxic trimix
Certify divers within RAID normoxic limits
Prepare divers for progression into hypoxic trimix training
You can now progress into:
RAID CCR Instructor pathways
RAID Pro-level upgrades
Your instructor development is delivered and evaluated by a RAID Instructor Trainer with extensive experience in deep open-circuit decompression and mixed-gas instruction.
Decades of international teaching and professional diving experience
Clear, structured, disciplined instructor development
Expertise across recreational, technical, and rebreather instruction
A supportive but high-standard approach to instructor evaluation
Real-world focus on safety, precision, and consistent performance
The objective is to produce instructors who are technically credible, calm under pressure, and trusted by their students.

Instructor training begins with application review, verification of experience, and coordination with a RAID Instructor Trainer.
