The original date from which IA Certification Seminar norms were to become mandatory for IA applications was 1/7/2022. Prospective IA applicants may be pleased to know that this date has recently been pushed back by 18 months to 1/1/2024:

Currently, IA title applications require 4 norms from eligible tournaments. IA title applications to be judged on or after 1/1/2024 will require 5 norms, exactly one of which must be obtained by attending an IA Certification Seminar and achieving a positive readiness evaluation.
