There are two ways to participate:

  1. Participant

1. Participants (Limited to 16 participants, there’s screening process)
This program allows 16 carefully selected participants to receive direct coaching from Ivana Chubbuck on stage after undergoing 6–8 hours of rehearsal in advance. Participants will not only participate in the masterclass on March 1 and 2, but also engage in two weeks of assigned rehearsals, enabling them to master the practical application of the Chubbuck Technique in a short period.
Applicants for the Participant need to pay as an active auditor first, then submit your documents including headshot and resume and video audition monologue. If you are not selected as one of the 16 participants, you will still be eligible to attend as an Active Auditor.

2. Active Auditor
Active Auditors will develop a deep understanding of the Chubbuck Technique and elevate their acting skills to a world-class level through practical, interactive exercises. These exercises—based on Ivana Chubbuck’s direct coaching of the participants—challenge active auditors to consider how they would approach the scenes themselves. Activities include techniques for accessing your emotions by tapping into your subconscious and building intimate relationships with someone you’ve just met. This program is designed for all active auditors to experience hands-on learning.
