SIS Resources is owned and operated by Matt Freund. The business consists of this site and two others - sqlReports.net and sisresources.org:
sqlReports.net is home to sqlReports, a free customization created in 2009 for use with PowerSchool. sqlReports allows users to create custom reports and charts similar to the ones in the screenshot below (the data in the screenshot is fictional and based on a training database from PowerSource). It's one of the most popular customizations in use and has hundreds of users. The site features the free download of sqlReports, 30+ free reports, and 200+ premium reports. Over 250 districts / organizations from around the world subscribe to the premium areas of the site.
sisresources.org is home to downloads and articles created by Matt Freund regarding two important areas of PowerSchool - customizations and data mining. Downloads and articles have been a longtime feature of the SIS Resources company, dating all the way back to 2007. Many of the articles on the site were used by Matt in presentations at user conferences, but some of the articles are brand new. Everything on the site is free, although an account is required to access some of the downloads and articles.
You can reach Matt Freund by emailing him at matt @ sisresources.com. He will try to respond to all emails received during weekday business hours (9 am - 5 pm CST) as soon as possible, however, there may be a delay in responding at times due to travel. Emails received on a weekend may not be answered until the following Monday.
If you have not received a reply within 24 hours*, please be sure to check your spam folder first, and if nothing is there, please email Matt again. Please make sure your email server allows emails from the sisresources.com domain and your email inbox does as well, so that any replies do not end up in your spam or junk folder.
*Emails that are business related or deal with sqlReports.net subscriptions will be given first priority. If you're looking for free help regarding PS, customizations, or SQL, those emails will be given low priorty and may take several days to answer, if at all. You should instead post those types of questions to the National PSUG user group or to PowerSource forums.
