For items 1-4: This information is easily available within the Agency’s Vigilant Solutions LEARN system. The simplest way to extract this data is to generate an “Agency Data Sharing Report” PDF file from within LEARN. To do this, a user may simply go to the “Sharing” section of LEARN and select “Output Report.” A CSV/XLS file containing these records would also satisfy this request. The instructions for extracting this data is described on pages 62-63 of the LEARN Agency Manager Guide, which may be found at this link: https://www.documentcloud.org/documents/3860685-LEARN-5-1-Agency-Manager-Guide.html

For items 5-10: This information is easily available within the Agency’s Vigilant Solutions LEARN system. The simplest way to extract this data is to generate a “Dashboard Hit Ratio Report” PDF file from within LEARN. We would prefer the data for each year to be provided separately. The instructions for extracting this data is described on pages 78-79 of the LEARN Agency Manager Guide, which may be found at this link: https://www.documentcloud.org/documents/3860685-LEARN-5-1-Agency-Manager-Guide.html

The requested documents will be made available to the general public, and this request is not being made for commercial purposes.

In the event that there are fees, I would be grateful if you would inform me of the total charges in advance of fulfilling my request. I would prefer the request filled electronically, by e-mail attachment if available or CD-ROM if not.

Thank you in advance for your anticipated cooperation in this matter. I look forward to receiving your response to this request within 10 calendar days, as the statute requires.

Sincerely,

Dave Maass
