How to become an ADI: your step-by-step guide from first thought to qualified
Thinking about a career change that fits around life and makes a real difference on local roads? Becoming an Approved Driving Instructor can be rewarding, flexible, and in steady demand across Teesside.
This guide walks you through the full journey in the UK, from first checks to Parts 1, 2, and 3, trainee licence options, realistic timelines and costs, and what to expect when you qualify.
You will also see how The ADI National Training Academy supports you at every stage with one-to-one mentoring, mock tests, supervised teaching, CPD, and post-qualification diary support.
ADI vs PDI explained
ADI means Approved Driving Instructor. You are fully qualified and on the Driver and Vehicle Standards Agency register.
PDI means Potential Driving Instructor. You have passed Parts 1 and 2, are training for Part 3, and may teach on a trainee licence to gain real experience.
Most career changers become a PDI first, then complete Part 3 to gain ADI status. At The ADI National Training Academy, we help you choose the best route for your circumstances.
Can you apply? Eligibility and common blockers
Before you book training, check you meet DVSA entry rules:
- You must be at least 21.
- You must have held a full UK or EU driving licence for 3 years minimum, with no bans in that period.
- Your eyesight must meet the 20-metre number-plate standard, with glasses or contacts if needed.
- Criminal record checks are required. Some convictions can bar entry, others may be acceptable. If unsure, ask the DVSA or speak with us for guidance on the process.
If you have more than 6 penalty points, a recent ban, or serious offences, speak to a trainer before investing. We will be honest about your prospects.
The three ADI tests, step by step
The ADI qualification has three parts. You must pass each in order.
Part 1: theory and hazard perception
What it covers: Highway Code, traffic law, road signs, and instructional knowledge, plus a hazard perception test using video clips.
Format: Multiple choice questions and computer-based hazard perception. Both sections must be passed together.
Study time: Many candidates prepare in 4 to 8 weeks with regular study. We provide a structured plan, mock tests, and hazard perception coaching.
Fees: The DVSA Part 1 fee is typically modest. Add training materials or classes as needed.
Our integrated theory support mirrors DVSA standards and links knowledge to local routes around Middlesbrough, Redcar, and the A66/A19 so it stays practical.
Part 2: driving ability
What it covers: Your advanced driving skills, planning, observation, and control on a challenging route.
Standard: Higher than the learner test. You must show consistently safe, smooth driving and professional judgement.
Preparation: Targeted coaching drives, mock tests, and feedback on common pressure points.
Attempts: You have up to 3 attempts at Part 2.
We run realistic mock tests to DVSA marking. You will practise across mixed Teesside roads so test day feels familiar.
Part 3: instructional ability
What it covers: Your ability to plan, deliver, and adapt a lesson. The examiner observes you teaching a real pupil.
Focus: Risk management, clear goals, timely feedback, and tailoring to your pupil.
Routes to build experience: Teach as a PDI on a trainee licence, or progress directly to Part 3 if you have enough supervised practice.
Attempts: You have up to 3 attempts at Part 3.
Our supervised teaching, observation sessions, and detailed feedback help you build a repeatable lesson structure that meets the DVSA standard.
Trainee licence route: teach as you learn
A trainee licence, often called a pink badge, lets you teach pupils for pay as a PDI after you pass Parts 1 and 2. It runs for 6 months.
It is a good route if you want real experience before Part 3, but it comes with conditions:
- You must receive ongoing training and log it.
- You are expected to attempt Part 3 during the licence period.
- You commit to professional standards from day one.
We will help you decide if the trainee licence suits your timeline and provide the supervised teaching you need to progress.
How long does it take to qualify?
Timelines vary with work and family commitments, test-date availability, and study time.
Typical ranges we see in the North East:
- Part 1 study and pass: 1 to 2 months for steady study.
- Part 2 training and pass: 1 to 3 months depending on current skill level and test slots.
- Part 3 training and pass: 2 to 6 months, faster if you teach under a trainee licence.
Overall, many candidates qualify in 6 to 12 months. Some are quicker; others take longer due to test waits or busy schedules.
We build a plan that fits your pace.
How much does it cost to become an ADI?
Expect two cost groups:
- DVSA fees: Paid for Parts 1, 2, and 3, plus the trainee licence fee if you choose that route. Fees are set nationally and can change, so check the DVSA site for the latest totals.
- Training: This covers coaching drives, theory support, mock tests, supervised teaching, and materials. Packages vary by candidate and route. We will map a plan to your needs and budget so you only buy what adds value.
We are transparent about costs before you start. If you later join our franchise, the optional diary-filling service is £75 per week, with no long contracts.
Is the ADI test hard?
It is challenging. The standard is higher than the learner test and you must be consistent.
That said, with the right preparation, most committed trainees pass.
Success typically comes from:
- A structured study plan for Part 1.
- Honest feedback and realistic mock tests for Part 2.
- Supervised teaching, observation, and clear lesson planning for Part 3.
We do not promise quick passes, but we do provide the support and practice that typically lead to strong results.
Demand and earning potential in Teesside
Learner demand across Middlesbrough, Stockton-on-Tees, and Redcar remains steady, with peaks around school and university holidays.
Newly qualified ADIs typically build a full diary in stages.
Earning potential varies with:
- Hours worked
- Lesson prices
- Car and fuel costs
- Whether you run independently or join a franchise
- Local demand
- Cancellation management
Our team helps you model realistic income and manage your diary efficiently.
If you later want support filling your diary, our franchise offers local advertising, leads in your chosen area, and admin back-up.
The weekly diary service is optional and set at £75 per week.

What success typically looks like
Many career changers start with a clear weekly routine: fixed study slots for Part 1, one or two coaching drives a week for Part 2, then a trainee licence to gain Part 3 teaching experience.
They track lessons delivered, reflect on risk management, and refine lesson plans based on mentor feedback.
That steady rhythm usually builds confidence and consistency, which is exactly what examiners look for.
