[[abstract]]Abstract This research aims at investigating the present status of high school physics teachers’ teaching ability as well as their expertise. To reach the purpose, this research adopts mainly the research method of questionnaire survey. A symposium of scholars, experts and high school physics teachers is held to ensure the credibility and effectiveness of the questionnaire survey. Questionnaires exploring the present status of teaching ability, expertise and opinions of high school physics teachers are given out to physics teachers in 90 public and private high schools. The effective samples are from 149 teachers. All materials are analyzed by SPSS for Windows 12.0. The conclusion is as follows: 1. The physics teacher of high school has utilized Flash or EasyJava software to make physics teaching materials in a low proportion of 24.8%. 2. Shown by the result of this research, high school physics teachers hold very different views toward indicator 9, “ I think at least half of my students are suitable to have scientific and technological careers.” There is great difference between conventional cognition and the investigation result. Hence, 3 suggestions are proposed as follows: 1. This research constructs 16 indicators of 4 indicating categories of development, which are effective and credible measurement items and they are suitable for high school physics teachers to use as tools to promote their teaching ability as well as improve their expertise. 2. It is suggested that high school physics teachers ponders over their roles again. They are encouraged to become an omni-directional good teacher to educate talents and to guide and support the less advanced . 3. The suggestions for the future researcher are: First, research and develop the assessment indexes for physics teaching in high schools. In terms of research subject, the coverage is suggested be inclusive of the physics teachers in public and private high schools nationwide in order to ensure the inference and representativeness. Then, enhance the collection and analysis of the interview materials in order to improve the objectivity. Finally, in research content, further researches are encouraged to work on designing indication items for assessment in terms of numbers of theses, papers, writings, awards, or even the manufacturing of teaching materials.
