TAV of Arabic Language Measurement

One of the many problems faced by second language students is the size of vocabulary. The aim of this study is to build a test to measure students ’ Arabic vocabulary size namely Test of Arabic Vocabulary (TAV). This research will then measure the validity and reliability of the test. The methodology of research involves the construction of tests, test items refinement process and the process of investigating test reliability and validity. Sample of research includes 33 pre university students of an Islamic secondary school in Temerloh, Pahang, Malaysia. This research is directed to follow an internal consistency test to observe the reliability of co-efficiency that is the correlation value of tests and retest, and the value of alpha Cronbach and Cohen Kappa. Results show that the value of correlation is high, that is.842, and the co-efficient of alpha Cronbach is high,.895, whereas the co-efficient of Cohen Kappa is also high,.95. Proof of content validity is reviewed by panel experts. The implication of this study is that the test can be used to measure TAV due to the test meeting criteria of reliable and valid psychometric characteristics
