This paper reports the results of the TOEIC® Speaking and Writing IP test administered by the Institute for Foreign Language Research and Education at Hiroshima University. In response to Hiroshima University’s accreditation by the Ministry of Education, Culture, Sports, Science and Technology as one of the 13 universities involved in the “Top Global University Project” in 2014, the administration of the TOEIC® Speaking and Writing IP test was initiated at our institute to evaluate the outcomes of a small-scale English language accelerator program launched in 2016. The program was discontinued after two years, but the TOEIC® Speaking and Writing IP test continued to be administered for four consecutive years, until 2019. This paper reviews the program from 2016 to 2017 and describes its integration into the mainstream curriculum in 2018 and 2019. When looking at the overall results for speaking and writing, 2019 was the most accomplished year. The results showed that students were able to improve their scores in a relatively short period of time. However, the improvement in writing scores was smaller than those in the previous three years.
