Affadavits can be downloaded from the above websites. Notary service currently is $2.00 per signature at the UPS Store in Fry's Marketplace at Combs/Gantzel. Fill the affadavit out in advance, but don't sign it until you're with the notary. Remember your state-issued ID! Also, unless you have multiple originals of your child(ren)'s birth certificate(s) it is recommended to hand-carry your affadavit(s) and birth certificates to the Superintendent's office in your county. While the office *will* mail back your originals if you include a SASE, things do get lost in the mail and replacements are not inexpensive.
According to A.R.S. 15-802 "Every child between the ages of six and sixteen years shall attend a school and shall be provided instruction in at least the subjects of reading, grammar, mathematics, social studies and science. The person who has custody of the child shall choose a public, private, charter or home school..."
It also goes on to include that parents may elect to delay education until age 8, but to do so legally, they must write a letter to the Superintendent's office explaining their election.
