Hello @Alicia Leon,
I'm so sorry you're having a hard time with the Instructional Support domain, I know how frustrating that is! I'm curious to see if anyone else has any tips or suggestions for you on how to work through it, I'm also happy to hear you reached out to get Reliability Support. That will be a huge help! In the meantime, we have some blogs on the dimensions within the IS domain that I thought could be helpful. Let me know if there's anything else I can help with!
Warmly,
Rachel
