Basic Reading Word Reading
The examinee reads a set of single words out loud. This subtest measures the speed and accuracy of single word reading.

Pseudoword Decoding
The examinee reads out loud a set of single non-words. This subtest measures the speed and accuracy of decoding skills.

Maths Problem Solving
The examinee listens as the examiner reads each problem, looks at the corresponding visual stimuli, and provides oral and/or points to responses. This subtest measures maths problem-solving skills under untimed conditions.

Numerical Operations
The examinee is asked to complete the numerical operations by writing the answers in the provided response booklet. This subtest measures written mathematics calculation skills under untimed conditions.

Maths Fluency
The examinee completes as many problems as he/she can within a 60-second time limit. This subtest measures written mathematics calculation fluency (speed and accuracy).

Listening Comprehension
In the first component of listening comprehension, the examinee looks at a set of pictures, listens to a word spoken out loud by the examiner, and then points (or states the letter that corresponds to) the picture that best illustrates the meaning of the target word. In the second component, the examinee listens to an audio recording of one or more sentences of a narrative or expository information, listens to the question(s) read out loud by the examiner, and then orally answers the question(s). This subtest measures listening comprehension at the level of the word, sentence, and discourse.

Oral Expression
The examinee is evaluated on his/her skills in association with expressive vocabulary, oral word fluency, and sentence repetition. This subtest measures the skills and competencies that are important for effective oral expression and that underlie written language skills.

Reading Comprehension & Fluency Reading Comprehension
The examinee reads each passage out loud or silently, listens to each question asked out loud by the examiner, and orally answers each question with the passage available for reference. This subtest measures literal and inferential reading comprehension skills using a variety of passage and question types that resemble those used in school settings.

Oral Reading Fluency
