How do I get started?

Most of this information can be found in the IGDI Descriptions section of the website. The Training section, also provides valuable information about the steps required to become a certified assessor.
  2. Second, request and engage the Child Performance Data System services you wish to use by contacting Dr. Dale Walker

What are the costs?

Answer: There are no costs to download and learn to use the IGDI instruments through this website.

Data processing and reporting costs are $1 per student. Once you have arranged for training and have completed the certification requirements you will be given access to the system for data entry and reporting. Contact Dr. Dale Walker to arrange for these services.
