Re-joining the Institute

If you were an Associate member or affiliate you will need to just complete the joining process again and pay the reinstatement fee which is detailed in the subscription and fees document below.

If you attained the status of MCIAT and allowed your membership to lapse for less than three years, to reinstate your membership you will need to complete the joining process again and submit your previous CIAT registration number or proof of former membership along with the reinstatement fee which is detailed in the subscription and fees document below. 

If you qualified as a Chartered Architectural Technologist and allowed your membership to be inactive for more than three years, to reinstate your membership you must complete the professional practice units (15-17) of the Chartered Architectural Technologist POP Record, followed by successful attendance at a Professional Practice Re-entry Interview. Before completing these units, you will need to re-join as an affiliate or Associate (depending on your eligibility). In order to re-join, you need to complete the joining process here and submit your previous CIAT registration number or proof of former membership along with the £70 reinstatement fee and applicable pro-rata subscription.

The purpose of the Professional Practice Re-entry Interview is to enable us to ensure you have retained your competence during the period your membership has been inactive.
