Teachers' sense of efficacy, or the belief that teachers have of their capacity to make an impact on students' performance, is an unexplored construct in deaf education research. This study included data from 296 respondents to examine the relationship of teacher and school characteristics with teachers' sense of efficacy in 80 different deaf education settings in the US. Deaf education teachers reported high overall efficacy beliefs but significantly lower efficacy beliefs in the area of student engagement than in instructional strategies and classroom management. Teachers' years of experience showed a significant relationship with efficacy beliefs, yet it was the teachers' perceived collective efficacy of their educational setting that ultimately predicted teachers' sense of efficacy. These findings lend credence to the need for further examination of school processes that influence teacher beliefs and attitudes in deaf education settings.

Students who are deaf or hard of hearing (SDHH) often need accommodations to participate in large-scale standardized assessments. One way to bridge the gap between the language of the test (English) and a student's linguistic background (often including American Sign Language [ASL]) is to present test items in ASL. The specific aim of this project was to measure the effects of an ASL accommodation on standardized test scores for SDHH in reading and mathematics. A total of 64 fifth- to eighth-grade (ages 10-15) SDHH from schools for the deaf in the United States participated in this study. There were no overall differences in the mean percent of items students scored correctly in the standard vs. ASL-accommodated conditions for reading or mathematics. We then conducted hierarchical linear regression analyses to analyze whether measures of exposure to ASL (home and classroom) and student proficiency in the subject area predicted student performance in ASL-accommodated assessments. The models explained up to half of the variance in the scores, with subject area proficiency (mathematics or reading) as the strongest predictor. ASL exposure was not significant with the exception of ASL classroom instruction as a predictor of mathematics scores.
