This study investigated educational provision and learner self-report factors associated with exam success for adult learners of British Sign Language (BSL) studying either Level 1 or Level 2 courses. These levels are equivalent to the first and second year of a United Kingdom General Certificate of Secondary Education (GCSE) qualification. Two hundred and thirty five students from three further education colleges answered a self-report questionnaire covering a range of variables. Analysis of the data suggests that: 1) success rates differed markedly for Level 1 and 2; 2) enhancements of educational provision, such as the use of extra conversational classes, appeared to play a role in increasing exam success rates; 3) individual factors associated with exam success varied between course level and between types of provision; 4) variables related to exam success at Level 2 were more numerous and more specifically related to the learning of sign language than those seen at Level 1; 5) Effect sizes seen for enhancements of educational provision were larger in size than for individual characteristics. These results offer insights into the factors that affect the success rates of people learning sign language.2 Adult college learners of British Sign Language: educational provision and learner self-report variables associated with exam successThe second half of the 20 th century has seen the growing recognition of the linguistic status of sign languages. One consequence of this has been the emergence of the formal teaching of sign language as a second language (L2). For American Sign Language (ASL), the most researched of the sign languages, this began in earnest in the early 1970s (Peterson, 2009), and now it is the fourth most popular language studied at US colleges and universities (Furman, Goldberg & Lusin, 2010).Learning any language as an L2 in adulthood is difficult; progression through levels requires increasing effort and learners usually stop short of native level proficiency (Dörnyei 2005). Binkley (2011) reports that the US Foreign Service Institute (FSI) & Defense Language Institute (DLI) have proposed four categories of L2 learning difficulty for native English speakers, with higher levels being more difficult. ASL difficulty estimates include category 2 (Francis, 1980, cited in Kemp, 1998) and category 4 (Jacobs, 1996.What is consistent across these two positions is that ASL does not fall into the easiest level category.Given the popularity of sign language courses and their apparent difficulty for L2 adult learners, it is important to understand the factors that impact on learning sign language. However, McKee, Rosen and McKee (2014) note that, despite the progress made in the scientific understanding of the linguistic and cultural properties of sign languages in recent decades, 'knowledge in the sphere of sign language teaching remains scarcely documented' (p. 1). As a result, sign language teaching has relied upon the generation and sharing of tutor insight rather than evidence-based teaching pract...
