Teachers of students with visual impairments (TVIs) act as the primary gatekeepers of AT for these students. Unfortunately, only about 40% of TVIs integrate AT into their practice. Efforts to predict TVIs\u2019 AT proficiency based on their preservice training have been unsuccessful. The current study proposes and confirms that TVIs\u2019 AT proficiency is related to their identification with a social community of practice (CoP) that values AT. Results from<jats:italic>n<\/jats:italic>= 505 North American TVIs produced a Spearman\u2019s correlation of \u03c1 = 0.49 between estimated AT proficiency and CoP identification. The relationship was strongest among TVIs with lower AT proficiency and CoP identification. Results have implications for industry, researchers, teacher preparation programs, personnel who administer and train assistive technologies, and policymakers concerned with ensuring that AT is available to students who have visual impairments. Mere availability of AT is insufficient to ensure its successful introduction to K-12 students with visual impairments, which relies on TVIs\u2019 AT proficiency for meaningful implementation. Developers and advocates of AT for K-12 students with visual impairments must consider the social context in which AT proficiency develops and provide appropriate social supports.<\/jats:p>","DOI":"10.1145\/2999569","type":"journal-article","created":{"date-parts":[[2016,11,9]],"date-time":"2016-11-09T13:36:49Z","timestamp":1478698609000},"page":"1-27","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":9,"title":["Social Predictors of Assistive Technology Proficiency Among Teachers of Students with Visual Impairments"],"prefix":"10.1145","volume":"9","author":[{"given":"Valerie S.","family":"Morash","sequence":"first","affiliation":[{"name":"The Smith-Kettlewell Eye Research Institute, San Francisco, CA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yue-Ting","family":"Siu","sequence":"additional","affiliation":[{"name":"San Francisco State University, San Francisco, CA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"320","published-online":{"date-parts":[[2016,11,7]]},"reference":[{"key":"e_1_2_1_1_1","doi-asserted-by":"publisher","DOI":"10.1177\/0145482X0209600204"},{"key":"e_1_2_1_2_1","doi-asserted-by":"publisher","DOI":"10.1177\/0145482X0810200602"},{"key":"e_1_2_1_3_1","doi-asserted-by":"publisher","DOI":"10.1080\/01621459.1979.10481038"},{"key":"e_1_2_1_4_1","doi-asserted-by":"publisher","DOI":"10.1177\/0145482X0409800704"},{"key":"e_1_2_1_5_1","doi-asserted-by":"publisher","DOI":"10.1177\/0145482X9809200508"},{"key":"e_1_2_1_6_1","doi-asserted-by":"publisher","DOI":"10.1080\/01621459.1987.10478410"},{"key":"e_1_2_1_7_1","first-page":"7","article-title":"A survey of teachers of students with visual impairments: Responsibilities, satisfactions, and needs","volume":"36","author":"Griffin-Shirley Nora","year":"2004","journal-title":"RE: View"},{"key":"e_1_2_1_8_1","first-page":"25","article-title":"The core curriculum for blind and visually impaired students, including those with additional disabilities","volume":"28","author":"Hatlen Phil","year":"1996","journal-title":"RE: View"},{"key":"e_1_2_1_9_1","volume-title":"Psychological Testing: Principles, Applications, and Issues","author":"Kaplan Robert","year":"2008","edition":"7"},{"key":"e_1_2_1_10_1","doi-asserted-by":"publisher","DOI":"10.1177\/0145482X0209600205"},{"key":"e_1_2_1_11_1","doi-asserted-by":"publisher","DOI":"10.1177\/0145482X0910300805"},{"key":"e_1_2_1_12_1","doi-asserted-by":"publisher","DOI":"10.1177\/0145482X1110500405"},{"key":"e_1_2_1_13_1","doi-asserted-by":"publisher","DOI":"10.18637\/jss.v020.i09"},{"key":"e_1_2_1_14_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1467-9620.2006.00684.x"},{"key":"e_1_2_1_15_1","unstructured":"Jum C.
