Therefore, the data the Department would receive would not be complete.”

Pennsylvania data taken from:
2007-2011: Statistics taken from data sent via email correspondence with Rosanne Cramer, PDE Division of Data Quality (email sent to ra-ddqadmin@pa.gov). Taken from data sent via email correspondence with Suzanne Tallman, Home Education & Private Tutoring Advisor (RA-home-education@pa.gov)

2012-2016: Taken from correspondence with RA-home-education@pa.gov, “A number of years ago the individual in the Division of Data Quality retired who was responsible for this collection and was not replaced. The responsibility eventually was shifted to the School Services Office where there also was not enough staff to maintain the collection. In 2015, we incorporated the Home Education and Private Tutoring Report into the PIMS collection so we expect that the collections will resume. If eventually we are able to reconstruct the information from previous years, we will. The best thing you can do is to check periodically the Data & Statistics webpages for Home School Education in Pennsylvania for updates. That is where the information will be posted.
