Designing a grammar test, among other tests, for classroom use requires much effort and the results need to be tested for reliability to ensure that it gives teachers the information they need about their students’ achievement and to make sure students are fairly scored. However, the data shows that most of the tests given to students to measure their performance were not tested for their reliability. It seems that teachers, as well as lecturers, do not bother with the reliability test or do not have the knowledge or opportunity to conduct the test. Therefore, this paper presents a way to design a reliable test without having to test for its reliability by using corpora such as COCA and BNC. After designing two sets of TOEFL-like grammar test, the writer pilot tested for their reliability to prove that this way of designing a test was effective. Then, the results were compared with the reliability of TOEFL grammar designed by the ETS, the official TOEFL test designer. The analysis results showed that the reliability of designed tests was .85 and .88. The results of this comparison showed that the grammar tests designed by using a corpus was very similar to those designed by the ETS, i.e. .86, proving that the designed tests were reliable, thus did not require any reliability test. Therefore, it is recommended that teachers use a corpus in designing a grammar test when a reliability test is not considered as an option for obtaining a reliable test
