Pack of 25 Examiner Record Booklets for the LCT-A: NU. The Listening Comprehension Test-Adolescent: Normative Update (LCT-A: NU) evaluates a student’s abilities in specific listening comprehension skills. Teachers can use the results to help students improve their skills and behaviors in both the classroom and in everyday listening situations. There are five subtests: Main Idea, Details, Reasoning, Vocabulary and Semantics, and Understanding Messages. Students are required to (a) pay careful attention to what they hear, (b) listen with a purpose in mind, and (c) remember what they hear well enough to think about it. Students must also avoid being impulsive in giving answers, and they must express answers verbally.
