Testing is an important part of teaching any language and an important part of learning a language. Vocabulary size test is one of placement tests that is used to determine the level of lexical knowledge of language learners .This test is designed in many languages and its vacancy was felt in the Persian. To design a vocabulary size test, one must pay attention to the frequency of the words used and linguistic corpus. The corpus used in this research is including paper texts in seven different fields. To design this test for each group of words, 80 questions were designed and arranged from high-frequency to low-frequency. The questions were computerized and the link was sent to the language learners. 130 people answered the test. 45 language learners also participated in the retest. Analysis showed that the mean test scores increased with the language level of the language learners. Skewness and Analysis of variance also showed that the data distribution was normal and the difference between the mean scores of different groups of novice, elementary, intermediate and advanced in this test was significant. Calculation of the correlation between test scores and retest scores indicates a strong correlation and test reliability. The interpretation of the scores of different language levels was also done and it was determined that each language level of the score can determine which language level. Based on this research, it can be said that the vocabulary size test can determine the language level of language learners as a placement test.

One of the key features of a successful test is to have an appropriate reliability. This study determined the validity and reliability of the Persian language placement test of Sa’adi Foundation. This test consists of three main sections: language knowledge, writing and speaking. The language knowledge section consists of three sub-sections: grammar, vocabulary, and reading. The statistical population of the test consisted of 140 language learners from 41 countries. To calculate the reliability and the construct validity, Cronbach's alpha coefficient and Pearson correlation coefficient was used respectively. The reliability index in the language knowledge sub-sections’, grammar was 0.71, vocabulary was 0.817, reading was 0.861 and for the whole language knowledge was 0.916. The reliability of the two sections of speaking and writing was 0.749 and the total test was 0.895. Considering that the acceptable reliability index in Cronbach's Alpha method was at least 0.7, it was found that the test in various sections and sub-sections, and the test overall, had an acceptable reliability. The correlation coefficients obtained from the test sections, between language knowledge and speaking were 0.175, language knowledge and writing 0.186, and writing and speaking 0.602. Perhaps at first glance, test validity is not acceptable, but by comparing the correlation between the sub-sections of the language knowledge and the skills of speaking and writing, it can be concluded that the students have acted poorly in the productive skills, and this shows that in their educational background, they are concerned only with language knowledge or declarative knowledge, not the procedural knowledge.one of the application of this article is that Persian curriculum should focused on improving procedural knowledge of the Persian learner.
