Freshmen, Sophomores, and Juniors will participate in mandatory State Testing this April. No registration is required. This exam will be digital; students will be required to use their D225 issued Chromebook for testing.
GBN will administer the new Enhanced ACT. While ACT only requires English, Mathematics, and Reading sections (the "core" subjects on the ACT), the State of Illinois requires all 5 sections (English, Mathematics, Reading, Science + Writing) for the state test in April. National registrations allows the option of only taking the core subjects, while the science and writing sections are optional. For more information, please visit ACT's website.

No Plan/Accommodations Not on Plan
ACT and College Board have strict guidelines for documentation that is required to be included with a request for accommodations. The links below provide extensive details regarding the documentation needed for specific diagnoses.
Without providing all of the documentation described, it is likely that your child will not be approved for the requested accommodation(s). ACT and College Board review each request on a case-by-case basis. Even with submitting the requested documents, there is no guarantee that they will approve your student. As your child does not currently have a school-based plan and/or is not receiving the requested accommodation(s) in the school setting, an explanation must be provided from an outside professional as to why the accommodations are necessary at this time. The burden for providing documentation rests with the family.
For College Board accommodation requests please follow the directions listed in the College Board Accommodations section. When submitting the Google form state what accommodations you are requesting and attach the outside documentation.
For ACT accommodations requests please follow the directions listed in the ACT Accommodations section. When submitting the Google form state what accommodations you are requesting and attach the outside documentation.
Testing Day at GBN
If your student has been approved for accommodated testing, you will receive further detailed information from the Testing Coordinator, Ms. Maddy Bumbaris, as your assigned testing date approaches.
For questions, you can reach out at MBumbaris@glenbrook225.org.
