Description

MIAST — Member of the Institute for Architectural Science and Technology — is a professional designation recognising individuals who have demonstrated technical knowledge, relevant industry experience and continued professional development in façade design and engineering. Eligibility is based on defined criteria and verified against IAST assessment, qualification and CPD records.

This application is your route to MIAST. If you have passed the Knowledge Assessment, completed eligible IAST CPD, or hold an IAST qualification, and have relevant industry experience, you may already meet the requirements. Simply confirm the route that applies to you, and we will verify your eligibility against our records.

As expectations for professional standards across the built environment continue to rise, demonstrating relevant experience, maintaining current technical knowledge and undertaking continuous professional development are increasingly important. Once awarded, MIAST gives you the right to use the MIAST post-nominal and provides you with a verifiable digital credential that clients, employers, principal contractors and other industry stakeholders can check online.


Open to current IAST Façade Intelligence Professional Members (FI PRO).

MIAST - Certificate of Professional Membership

Your credential, verified.

On successful completion, you'll receive a Certificate of Professional Membership — a formal, verifiable credential confirming your standing on the IAST Register of Facade Professionals. Every certificate can be independently checked against the Register, giving employers and clients instant confidence in your credentials. Membership is reserved for active professionals who commit to ongoing professional development, ensuring your certificate reflects not just a qualification, but a continued commitment to excellence in facades.

Why MIAST is different

Verifiable: A digital credential that can be independently checked online.
Current: Maintained through ongoing CPD, supporting the continued development of up-to-date knowledge and skills.
Façade-specific: Focused specifically on façade design and engineering and the building envelope, rather than generic construction.
For professionals and firms: Demonstrate individual knowledge, experience and professional development while strengthening your company’s professional credentials at pre-qualification and tender.

How we review your application

Every application is assessed by IAST against the requirements for your chosen route. We confirm your JCI Baseline result and your CPD record directly from our platform, review your stated experience and referee, and check your declaration. Where a qualification route applies, we confirm the award. If anything needs clarifying, we may contact you or your referee. Once satisfied, we award MIAST, issue your verifiable digital credential, and confirm your post-nominal.
