AAT levels explained: Level 2, 3 and 4

AAT’s accounting qualification has three levels. Level 2 covers bookkeeping basics, Level 3 covers financial statements, management accounting and tax processes, and Level 4 is the professional diploma that leads to full AAT membership. A new Level 4, the Diploma for Professional Accounting Technicians, replaced the old one for new students from 1 September 2026.

What are the three AAT levels?

The three AAT accounting levels are the Level 2 Certificate in Accounting, the Level 3 Diploma in Accounting and the Level 4 Diploma for Professional Accounting Technicians. Older names such as “Foundation Certificate” and “Advanced Diploma” belong to previous versions and are still used by some colleges.

These figures come from AAT’s qualification specifications page. In Scotland the same qualifications sit at SCQF Levels 6, 7 and 8.

What do you study at AAT Level 2?

Level 2 teaches double-entry bookkeeping, basic controls and costing. The Level 2 Certificate in Accounting has four units, each with a share of the overall grade:

• Introduction to Bookkeeping (25%)
• Principles of Bookkeeping Controls (25%)
• Principles of Costing (20%)
• The Business Environment (30%)

AAT says it usually takes around one year, and can be done in as little as six months. Typical jobs include accounts assistant, purchase or sales ledger clerk and trainee finance assistant.

What do you study at AAT Level 3?

Level 3 moves on to preparing financial statements, management accounting and business tax. The Level 3 Diploma in Accounting has four units:

• Business Awareness (15%)
• Financial Accounting: Preparing Financial Statements (40%)
• Management Accounting Techniques (30%)
• Tax Processes for Businesses (15%)

It also usually takes around one year. Passing Level 3 lets you apply for AAT bookkeeping membership (AATQB), which is a route to running your own bookkeeping business. See our guide to becoming a bookkeeper.

What do you study at AAT Level 4?

Level 4 is the professional level, covering company accounts, management accounting, audit and tax. The Level 4 Diploma for Professional Accounting Technicians has five mandatory units and no optional units:

• Financial Accounting (25%)
• Management Accounting (25%)
• Advanced Business Awareness (20%)
• Audit and Internal Controls (15%)
• Principles of Taxation (15%)

AAT says it usually takes 12 to 18 months. Passing it lets you apply for full AAT membership (MAAT). If you plan to offer services to the public, you can then apply to become an AAT Licensed Accountant or Bookkeeper; see our guide to the AAT licence. AAT says the new diploma was approved as a Higher Technical Qualification (HTQ) in England in August 2025.

What has changed at Level 4 in 2026?

The old Q2022 Level 4 Diploma in Professional Accounting is being withdrawn. It had three mandatory units and two optional units from a choice of five. AAT’s Level 4 timeline gives these dates:

1. 31 August 2026: registration closed for the Q2022 Level 4 diploma.
2. 1 September 2026: first teaching and registrations for the new diploma.
3. 21 September 2026: first assessments go live for Financial Accounting and Management Accounting.
4. 31 July 2028: last assessment date for the Q2022 diploma.
5. 31 October 2028: last certification date for the Q2022 diploma.

If you are partway through Q2022 Level 4, you can finish it by 31 July 2028 or transfer. Transfers carry over any number of units, but you must pass at least one assessment on the new diploma, and a £50 transfer fee applies until 31 July 2028. Assessments taken under the older AQ2016 version do not transfer.

Do you have to start at Level 2?

No. AAT says “students can start with any qualification depending on existing skills and experience”. It recommends a good standard of English and maths, and offers an AAT Skillcheck test for people with some accounting experience.

Use this to pick your starting point:

• If you are new to accounting, start at Level 2.
• If you already do bookkeeping at work or hold a bookkeeping qualification, take Skillcheck; you may start at Level 3.
• If you want to be a self-employed bookkeeper, Level 3 and AATQB may be enough.
• If you want to prepare company accounts or go on to ACCA or ACA, aim for Level 4.
• If you have an accounting or finance degree, check whether you qualify for exemptions.

How much does each level cost?

AAT’s own fees are a one-off registration fee plus a fee for each unit assessment. The Level 3 page lists registration at £244, which gives access for the qualification’s lifetime, typically four to five years, or £101 for AAT bookkeeping members.

Tuition is extra. AAT’s Level 3 page puts training provider fees at £900 to £2,000, and providers may add an admin fee per assessment. Our AAT fees guide has the full breakdown.

Where can AAT take you?

AAT Level 4 leads to MAAT membership and can be a stepping stone to chartered qualifications. Our guides compare AAT and ACCA and cover the whole AAT qualification.
