The rubric was tried out to the two instructors of Jogja English who were responsible to a class of 9 students and a class of 10 students. The try-out was
done on January, 20th 2015. Those two instructors were given the instruction to use the rubric in scoring the final test in the prior day. After that, before the

instructor used the rubric in the class, the researcher ensured that the instructors have understood how to use the rubric and asked them whether they had questions
or not. The instructors asked the researcher not to came into the class because the instructors afraid that the performance of the members would be decrease if they
had one new people in the class and felt more nervous. The researcher agreed that and then waited out of the class until the class was over. After that the researcher
conducted an interview with the insructors. Based on the interview, both of the instructors stated that the rubric was easy to use and helpful to evaluate the
members‟ performance. There were no significant problem appeared in the design and the use of the rubric. However, when the researcher asked about the
possibility to use the rubric to every speaking tasks, the instructors still were not sure about that because it needed more trial. The instructors themselves used
different tasks though the members were from the same level. The first instructor used the simulation activity by asking the members to make a conversation in pair
with selected topic, while the second one used the prepared talks activity by asking the members to present a product in front of the class then had a question
and answer session. After the try-out, the researcher then wrote the final draft of the rubric based
on the result of the interview with the instructors. The final draft can be seen on appendix.
