RIDA provides an alternative to meeting ARIDO’s examination requirement for registration in Ontario. The Practice Readiness Program and Entrance Interview ensures that all individuals applying to become a Registered Interior Designer in Ontario are provided a fair and equitable opportunity to demonstrate the competencies required to practice interior design while protecting the public interest. ARIDO recognizes its accountability as a Regulatory Body to advance equity and diverse representation through actionable initiatives.
The two-part assessment process focuses on practical application and advanced analysis & problem-solving across eight (8) competency areas of interior design practice
- Part 1: Practice Readiness Program (30 contact hours flexible online program with self-paced learning)
An online learning program covering key competency areas essential for successful practice. It is self-paced and aligns with ARIDO’s eight competency areas addressing relevant practice aspects. Candidates will also have the opportunity to develop a practice plan during this section of the assessment. - Part 2: Entrance Interview (45-minute oral test conducted virtually by one Chair and 2 Assessors)
A semi-structured oral assessment conducted by a Chair and two assessors. It evaluates the candidate’s ability to apply advanced analysis, problem-solving, and practical skills across ARIDO’s eight competency areas of interior design practice.
Competency areas are weighted to reflect their relative importance in assessing overall practice readiness.
