- Yes — abridged accounts (limited disclosure)

- Audit opinion
- Unqualified (clean)
- Going concern
- Affirmed
“The Trustees note that student and membership numbers continue to be flat and the economic outlook for the sectors our Members serve is poor at the current time. The Trustees are therefore aiming to get back to a break-even operating model within a reasonable timeframe. The charity currently has adequate liquid reserves that can be utilised to cover short to medium term downturns in the sectors we serve. They, therefore, have a reasonable expectation that the Association has adequate resources to continue in operational existence and will continue to meet its liabilities for the foreseeable future, being a period of at least twelve months from the date these financial statements are approved. The Members of the Council and Trustees continue to adopt the going concern basis in preparing the financial statements.”
