AAT Level 3 Advanced Diploma in Accounting

AAT Level 3 Advanced Diploma in Accounting 

The AAT Advanced Diploma in Accounting offers technical training in accounting and is ideal for anyone wishing to pursue a career in accountancy and finance.

This qualification is a progression route for students who have achieved either the AAT Foundation Certificate in Accounting or the AAT Foundation Diploma in Accounting and Business. It is also suitable for those who are at a more intermediate level and looking to develop their skills in accounting, or for those who have already started working in finance and who have a need and desire to attain formal recognition of their skills. 

The purpose of this qualification is to ensure that students are well prepared to progress into a career in business, finance or professional accountancy, or into further education. Students will learn and master financial processes including accounting principles and concepts, advanced bookkeeping and final accounts. They will also understand business issues regarding value added tax (VAT), issues in business, management accounting costing techniques and ethical practices for accountants. This qualification further delivers software skills through spreadsheet training for accounting. 


Are there any prerequisites for this qualification?

AAT does not set any prerequisites for the study of the AAT Advanced Diploma in Accounting. However, for the best chance of success, we recommend that students begin their studies with a good standard of English and maths. 

If students do have any other relevant school or college qualifications, a degree or some accounting experience, these may in certain circumstances entitle students to claim exemptions.


What does the qualification cover? 

The AAT Advanced Diploma in Accounting covers a range of complex accounting tasks, including maintaining cost accounting records and the preparation of reports and returns. It comprises six mandatory units: 

  • Advanced Bookkeeping
  • Final Accounts Preparation 
  • Management Accounting: Costing
  • Indirect Tax 
  • Ethics for Accountants 
  • Spreadsheets for Accounting. 

All of the units within this qualification are mandatory. Four units are assessed individually in end of-unit assessments. This qualification also includes a synoptic assessment that students sit towards the end of the qualification, which draws on and assesses knowledge and understanding from across the qualification.



Students must successfully complete four unit assessments and one synoptic assessment to achieve this qualification. 

The assessments in this qualification are computer based with a time restriction. Students will be presented with a range of question types and formats in the assessment. These may include multiple-choice questions, numeric gap-fill questions, or question tools that replicate workplace activities, such as making entries in a journal. In some assessments, questions will require a written answer, and this is particularly so in the synoptic assessments. 

How long is the course?

It will usually take around one year to complete this qualification, but this will depend on the study method and course timetable. It may be possible to complete this qualification in as little as six months.


The estimated learning hours for this course is 390 hours. This includes lectures, tutorials or supervised study. Although this is not compulsory for all learners; some students may need more or less support to achieve this qualification. 


It is recommended that the total qualification time is 520 hours. This includes learning hours, independent study and unsupervised learning.
