A colleague went on a PD, she arranged it herself and went in her own time and paid her own expenses. School (as far as I am aware did not know she was attending). At the PD she was given a free book, however, she needed a different grade book and this was sent addressed to her at school. School Admin opened her mail and said the book belonged to the school (it was then sent to the library and catalogued). According to Admin, she went on PD for work purposes and any materials gained from any PD belong to the school. She sees things differently and believes the book is hers (she doesn't want to have to buy a copy). So who owns the book? The school or the teacher?
