STATEMENT OF THE PROBLEM It is not fully known the extent to which the level of in-service teacher training in assistive technology for the blind and visually impaired and academic subject area affects the level of student access to and usage of assistive technology. Students who are blind and visually impaired often lack equal access to the same general curriculum as their sighted peers. Access is achieved through the use of assistive technology.
PURPOSE OF THE STUDY The purpose of this study was to examine the relationship between the level of in- service teacher training in assistive technology for the blind and visually impaired and academic subject area, with student access to and the level of usage of assistive technology in order to access the general education curriculum.
STUDY SUMMARY Correlational Study To determine if there was a significant correlation between o teacher in-service training and academic subject area Student levels of access to assistive technology for the visually impaired Student levels of usage of assistive technology for the visually impaired

HYPOTHESIS 1 RESULTS
Null hypothesis is retained. While there were a few areas that were statistically significant, there was not enough evidence to support the hypothesis. There were trends which indicate that further research with a larger sample size might give better results to support the research hypothesis.
HYPOTHESIS 2 H 2 : There is a significant relationship between the academic subject that the teacher of the visually impaired is teaching, and the level of student access by students with visual impairments to assistive technology for the visually impaired.
Null Hypothesis 2 H 0 : There is not a significant relationship between the academic subject that the teacher of the visually impaired is teaching, and the level of student access by students with visual impairments to assistive technology for the visually impaired.

HYPOTHESIS 3 RESULTS Spearman’s correlation coefficient indicates little to no correlation between the level of teacher in- service training in AT for the visually impaired and student usage of AT for the visually impaired in each academic subject area. Although there are a few areas that are statistically significant, there were not enough to warrant accepting the research hypothesis so the null hypothesis must be retained.

HYPOTHESIS 4 RESULTS Figure 6. Comparison of student assistive technology access by subject area n = 45.
HYPOTHESIS 4 RESULTS Based on the Spearman’s correlation coefficient, there is a significant correlation between usage of assistive technology for students with visual impairments and subject areas. In fact, there are numerous significant correlations between AT usage as compared to usage in other academic areas. Of the possible 156 correlational possibilities, 12 (7.7 %) were significant at the p <.05 level and 110 (71 %) were significant at the p <.01 level. Only 34 (21.3%) were not statistically significant.
HYPOTHESIS 4 RESULTS There were sufficient significant correlations at the p <.05 and p <.01 level (78.7% ) to determine that the research hypothesis was retained. The null hypothesis was rejected.
STUDY CONCLUSIONS Hypothesis 1 and Hypothesis 3- The null hypotheses were accepted. However, there were trends, though not statistically significant, for hypothesis 1 that indicated that further study might yield different results with a larger sample size. Hypotheses 2 and 4- The research hypotheses was retained.
RECOMMENDATIONS- FURTHER RESEARCH Replication of the study with a larger sample size. Include itinerant TVI’s. Expand study to examine TVI’s skill level in each assistive technology level and not just their number of hours of training
RECOMMENDATIONS- PRACTICE Include peer coaching as a follow-up to in- service training to improve TVI levels of proficiency TVI’s should provide access to a variety of assistive technology both high and low tech in all subject areas Access to the curriculum is the key to positive student achievement for students with visual impairments. AT is the catalyst that makes this possible.
CONCLUSION Access to and use of assistive technology is not a luxury for students with visual impairments. It is a necessity. The use of assistive technology is the key that unlocks the world of print and digital information to students with low vision and blindness. Further investigation is needed to strengthen the body of research in this critical area.
