The school year is defined as July 1 of the year until June 30 of the following year, with the exception of the Philadelphia City School District where it is defined as January 1 to December 31 of any year (24 P.S. § 1-102).
The school year defines when a home education program may begin counting days or hours toward compulsory attendance laws for the new school year (July 1) and when the portfolio and accompanying documentation is due at the end of the school year (June 30). Some parents may elect to have year-round homeschooling; this could begin on July 1, as long as the appropriate documentation is submitted to the district.
Although Philadelphia City School District's school year is defined as January 1 to December 31, they use the same calendar as the rest of the other school districts for homeschool affidavit submissions (August 1) and portfolio submissions (June 30).
