Here is a post on advocacy that I have copied and pasted across from OZTL posted
It’s vital to support arguments promoting school libraries and TLs with sound evidence. Demonstrate the outcomes of TL activity, school library programs etc – beyond listing input, ie. what you do.
Evidence can include: statistics, qualitative evaluations and anecdotal feedback. Even NAPLAN can be your friend! Real examples and quotes are particularly powerful.
Supplement the evidence you gather within your own school with research findings from wider afield, Australia and internationally. Look to: reports from Softlink; articles by researchers like Lyn Hay, Ross Todd, Barbara Combes; advocacy resources from organisations like ASLA, SLAQ, ALIA, The Hub<http://hubinfo.wordpress.com/tls/advocacy/>, AASL<http://www.ala.org/aasl/advocacy/resources>
This article summarises international research that provides compelling evidence about the impacts of TLs and school libraries on literacy and learning outcomes: Hughes, Hilary, Bozorgian, Hossein, & Allan, Cherie (2014) School libraries, teacher-librarians and student outcomes : presenting and using the evidence.<http://eprints.qut.edu.au/74876/> School Libraries Worldwide, 20(1), pp. 29-50.
This report provides evidence from Gold Coast schools: Hughes, Hilary E. (2013) School libraries, teacher-librarians and their contribution to student literacy development in Gold Coast schools.<http://eprints.qut.edu.au/60260/> SLAQ, Brisbane.
Ann Gillespie’s research demonstrates how TLs can be effective evidence based practitioners: Gillespie, Ann M. (2013) Untangling the evidence : teacher librarians and evidence based practice.<http://eprints.qut.edu.au/61742/> PhD thesis, Queensland University of Technology.
— and look out for her forthcoming article in Access
To help illustrate your points, here’s a great infographic from Library Research Service in Colorado http://www.lrs.org/2013/02/27/make-the-case-for-school-libraries-with-our-new-impact-studies-infographic/
Best of luck Hilary
