TOEFL iBT Teacher for App Testing

I run Exaaam, a live web app that grades TOEFL iBT speaking and writing responses on the 0-30 scale and gives students rubric-based feedback. Before I open it to more teachers, I want a working TOEFL iBT teacher to use it on real tasks and tell me where it falls short. What I need from you: Sign up and run the full flow the way you would with a student: assign speaking and writing tasks, submit responses, review the scoring and the feedback. Run responses of different quality levels through it and tell me where the score or the feedback feels off against how you'd grade it yourself. Flag anything that breaks or slows you down. Send a short written summary of what worked and what you'd change. A quick call to walk through it is welcome but optional. This is roughly 2-3 hours of work spread over a week or two. Requirements: You currently teach TOEFL iBT, or did recently, and know the speaking and writing rubrics well enough to judge a score on sight. You're comfortable being blunt about what isn't working. Pay is $50 fixed for the test and the write-up. On top of that I'll set you up with 3 months of free access to the full plan so you can keep using it with your own students.
