Hi
@Marlene Campos,
Are you referring to quizzes in the CDA with CLASS Course, or your CLASS Observation test?
If you are referring to the CDA with CLASS Course, I recommend reaching out to our Customer Support team at contact@teachstone.com. If you are referring to your CLASS Observation Reliability Test, you will need to re-attend training if you did not pass all three attempts.
I hope this is helpful, and please chat with us via the "Chat with Support" button in the lower right-hand corner if you have more questions we might be able to help you with!
Best,
Allison
