Materials and Methods: This study was performed in two parts: included development and standardization of the test and the second part was the evaluation stage. In the first section, Watson&aposs crieria fpr valid speech recognition tests for children was considered. In order to balance the lists phonemically, it was necessary to determine Persian phonemes&apos frequency -of- occurences. Thus, the frequency -of- occurences for 29 phonemes of Persian language in children&aposs and adults&apos speech were separately determined. There were significant differences between some phonemes&apos frequencies in the two samples. So&apos their frequencies in children&aposs speech was used to design the test. It should be mentioned that each list could contains only 25 vowels, while almost 32 ones were meeded according to the phonemically balancing procedure. Therefore, vowels and consonants were separately balanced. The required monosyllabic words were extracted from the books written for 4 to 6 years old children. Finally, four closed set (3- picture matrix) 25 word lists were prepared. The lists were recorded on magnetic cassette in one of the IRIB studios.To assess the test validity and reliabity, 33 normal hearing children were randomly selected from kindergartens over the city of Tehranand were tested at the Audiology Clinic of the Rehabilitation Faculty, Tehran University of Medical Sciences in 1998. The tests included: otoscopy, pure tone & immittance audiometry, establishing speech reception threshold, and speech recognition test - retest by these lists.
Findings: 1- Normal hearing children obtained 92-100 percent scores for each list at their most comfortable loudness levels through test - retest.
2- No significant difference was observed in test - retest scores in each list (p>0.05).
3-No significant difference obtained between the lists test or retest scores (p>0.O5).
4-No significant difference was observed between children&aposs scores in terms of their age and gender (p>O.OS)
Conclusion: this study, therefore, is reliable and valid. The lists are phonemically balanced and equal in difficulty. Due to the conditions under which the test was designed (including, phonemic balance, necessity of using the words that could be pictured and of the presence of tow other word in children&aposs vocabulary which is similar in auditory aspects), only the content validity for word familiarity decreased a little that could be overcome by introducing them through pictures prior to the start of the test.

Background and Aim: Valid identification, prevention, and treatment of language disorders have a high priority for the clinicians. Story retelling is a method for studying language development which is faster than other procedures in implementing and analyzing, and has a reliable scoring system. The aim of this project is to construct story retelling test for assessing language structure in 6-7 year old, Persian children.
Methods: An appropriate story for 6-7 year old children was written by the help of a speech pathologist, a linguist, and a novelist. The validity of the constructed story was checked by 14 experts. Then related pictures were design and their validity was examined. The test was conducted on 72 children (36 girls, 36 boys) of 6-7 years. The reliability was administered with a test-retest design with a two week interval. The reliability of the scoring system was evaluated with inter-rater method.
Results: Content validity index for this test was 89%, interclass correlation was 83%, and standard error of measurement was 2.76. The interclass correlation for scoring system was 93% and Pearson&aposs correlation was 90%. Correlation of the test-retest scores was statistically significant (p<0.01).
Conclusion: This story retelling test has appropriate validity and reliability. It is suitable for quick assessment of language structure in 6-7 year old, Persian children.
