Lack of formal tests for assessing Persian language proficiency is one of the main problems for speech and language pathologists in Iran. The purpose of this study was to generate an item pool for a syntax comprehension test based on the characteristics of the Persian language and Iranian culture, as well as the spoken variant for 4-6 years old native Persian speaking children. We first extracted 41 syntactic structures of Persian for the syntax comprehension test, of which 8 structures were excluded in the first phase. Then, 198 items were developed for the remaining 33 syntactic structures. To determine content validity, 14 experts assessed the structures and 12 experts expressed their views on the items. Content Validity Ratio (CVR) was calculated. 24 structures with CVR > 0.50 were selected. 107 items were selected based on their CVR value (CVR > 0.47). Eleven new items were regenerated to replace items with a CVR below 0.47. According to the results, the test turned out to have a good content validity.

Większość stosowanych w Polsce testów osiągnięć szkolnych pozbawionych jest mocnego uzasadnienia swojej trafności w postaci szczegółowej dokumentacji. Sytuacja ta wpływa negatywnie na rozwój metodologii konstrukcji tych narzędzi. Artykuł stanowi opis zestawu trzech standaryzowanych testów osiągnięć szkolnych TOS3 wykorzystanych w ramach dwóch badań. Testy te służą pomiarowi osiągnięć szkolnych z obszaru edukacji polonistycznej i matematycznej uczniów kończących I etap edukacyjny. W artykule przedstawiono proces konstrukcji testów osiągnięć z wykorzystaniem modelu Rascha (szczególnego przypadku jednoparametrycznego modelu IRT). Udokumentowano także trafność i rzetelność TOS3, wykorzystując wyniki dwóch reprezentatywnych badań (N > 5000). Artykuł pokazuje korzyści wynikające z wykorzystania modelu pomiarowego podczas budowy narzędzi. Opisane doświadczenia mogą być źródłem wskazówek dla twórców przyszłych testów osiągnięć szkolnych w Polsce.

Lack of detailed documentation on the majority of achievements tests used in schools in Poland has been a barrier to adequately establish their validity. This has presented an impediment to the development of such tests in Poland. The article contains the description of a set of three standardised school achievement tests, TOS3, which were used in two separate studies. The TOS3 tests were designed to measure school achievement in language (Polish) and mathematics after the first three years of school. The article describes the development of the tests using the Rasch measurement model (a special case of the 1PL IRT model). The validity and reliability of the TOS3 tests is also documented, based on the results of the two representative studies (N > 5000). The article describes the benefits of a choice of a measurement model at the stage of test development. The described methodology of TOS3 tests development may be of value to creators of future achievement tests in Poland.
