eSpark uses high quality, educational third party content that's curated and vetted by our team of former teachers. The most common reason students are blocked in accessing content inside and outside of eSpark is due to district network filtering restrictions. The following steps will ensure that your students will be able to access all educational content on eSpark. Please note, you may need to involve your tech coach or tech support to assist with this.

1. On a computer with the Chrome browser, please install the eSpark Link Checker Chrome extension using this link (espark.app/linkchecker). To make sure the Link Checker gives an accurate report, please run it on a device that has similar filtering to a student device on the student network. After you run the checker, it will give you a list of sites unblock from your district network filter or add to your allow list.

2. If the above process doesn't solve the issues, additional information about the eSpark app can be found below for your tech staff. eSpark communicates with a number of hosts over HTTP (TCP port 80) and HTTPS (TCP port 443). Please ensure the following hosts are accessible through your firewall and/or content filter:
