There is a section in the Admin that allows you to download the minimum requirement data (according to WA OSPI) as a csv and upload to OSPI.
In order to locate this spreadsheet of information, you have to be given Admin rights, as well as 504 Admin rights. Log into your district's Admin at (yourdistrict).schooldata.net/admin. From there navigate to 504 Admin >> Student 504 Plan Dates.
Once you select Student 504 Plan Dates, you will see listed: Student SSID, Name, 504 Implementation date, and Review Date. You can then select menu >> download as CSV.
