An instrument, either a self-developed, adapted or adopted, is the most important aspects of a research. In the main study, two instruments (1.Word Reading Test Kit and 2.A Reading Text) were adapted from other resources to assess the word-recognition accuracy. It is fundamental to test the validity and reliability of the instrument if it is self developed or adapted from any resources. The aim of this pilot study is to determine the validity and reliability of the two instruments for measuring the word-recognition accuracy. Two groups of samplings were selected. First, a group of 7 expert panels to get their feedback on face validity and content validity. The second was 8 Year 3 pupils to measure their scores for the test-retest reliability. The results showed that both instruments got 100% for 5 out of 8 criteria in the face validity which fell under the excellent category. For the content validity, both instruments obtained a high level of agreement among the 7 expert panels with (CVI =100%) for instrument 1 and (CVI = 98.57%) for instrument 2. In terms of test-retest reliability, the Pearson Correlation was r(8)=0.881 which indicated good reliability for the first instrument. Meanwhile, for the second instrument, the Pearson Correlation was r(8)=0.916. Thus, it indicated excellent reliability. After some minor amendment, the instruments were valid and reliable for data collection in the main study. A pilot study helped to identify the design flaws, gain experience and learn important information prior to undertaking the main study.
