With the deepening of reform and open door policy, vocational education has become more and more important. Secondary vocational schools shoulder the responsibility of training intermediate skilled talents for the country. However, vocational English teaching has become more difficult because of the reduction of students’ quantity and quality. Teachers have tried to find out better methods to suit students. Many researches have been done about English assessment. But, they mainly focus on the content of assessment, and put less importance to the processing of assessment data. After considering the fact that most vocational students are addicted to electronic games for a long time, the author put forward the assumption of visual assessment, and put it into practice. Basing on the comparative study of two parallel classes, the author found that visual assessment could improve students’ performance and had certain effectiveness for vocational English teaching.
