Researchers report on how C-test principles were applied in creating the new language tests, with careful attention to language-specific challenges and solutions. The final, five-text C-tests in all languages demonstrated impressive psychometric qualities as well as strong relationships with criterion variables such as learner self-assessments and instructional levels. These test development projects provide new tests for use by foreign language researchers, and they demonstrate innovative and rigorous test development practices in diverse languages.", "item_img_path" : "https://covers1.booksamillion.com/covers/bam/3/63/174/206/3631742061_b.jpg", "price_data" : { "retail_price" : "79.90", "online_price" : "79.90", "our_price" : "79.90", "club_price" : "79.90", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
