ILLINOIS HOMESCHOOLING LEGALITIES
Illinois homeschools are considered private schools; at the same level as any brick and mortar or other private school. The parent(s) function as administrator (principal/superintendent) and teacher/education facilitator. This legal determination came about via a 1950 Illinois Supreme Court ruling  that has prevailed. The Court ruled: that by receiving instruction in her home in the manner shown by the evidence the child [7 year old Levisen daughter] was attending a private school.
Homeschools in Illinois are not required to register their students with school district authorities, the Regional Superintendent’s office and/or the IL State Board of Education. Illinois homeschoolers’ exemption from public school compliance of Illinois School Code Chapter 105, Section 26-1 , requires that their child (from 7-17 years of age) does “attend a private or parochial school where the branches of education are taught in the English language to children of the same age and grade as in the public schools”. Your home is that “private school”.
If your child hasn’t attended public schools; no reporting, notification or documentation is required for the
public school system. If questions are asked by the public school authorities, a letter stating compliance with Section 26-1 may be sent to your Regional Superintendent.  Make sure that you confirm proof of delivery via a postal receipt and request that all school communications be in written form.
If withdrawing your child from public school to homeschool, a letter of transfer notification  is required of your private school as a transferee and should be provided to your child’s building principal transferor. Upon notification, the school should provide an ISBE Student Transfer Form  that will also confirm transfer notification.
Sample letters for transfer:

You may also request transfer of your child’s academic transcripts or medical records to your school’s address (your home address). This request can also be documented, without limitation, as proof of transfer enrollment. It must be written within 150 days of your child’s withdrawal from public school. If transfer proof is not provided, the public school can count your child as a dropout .
