Hello,
Thank you for your question!
At this time, I recommend reaching out directly to Teachstone Customer Support to inquire about any existing crosswalks between the CLASS® tools and the Desired Results Developmental Profile (DRDP) used in California. They’ll be able to confirm whether such a resource is available or point you toward the most relevant guidance.
You can contact them at:
📞 Phone: 866-998-8352
📧 Email: support@teachstone.com
Please let me know if there’s anything else I can support you with!
