Description:

The Test of Word Reading Efficiency–Second Edition (TOWRE-2) is a nationally normed measure of word reading accuracy and speed. The test contains two subtests: the Sight Word Efficiency (SWE) subtest, and the Phonemic Decoding Efficiency (PDE) subtest. The SWE subtest involves presenting the respondent with a list of real printed words. The respondent must accurately read and pronounce as many words as possible in 45 seconds. This subtest evaluates the respondents’ ability to identify sight words. The PDE subtest involves presenting a list of printed nonwords. The respondent must accurately decode and pronounce as many words as possible in 45 seconds. This subtest evaluates the respondents’ ability to decode (“sound out”) nonwords. The examiner scores each item as it is being pronounced.

Specific Instructions:

The Test of Word Reading Efficiency–Second Edition (TOWRE-2) is a proprietary protocol and administration requires a licensing agreement from Pro-Ed, Incorporated. For this assessment to be considered valid, the investigator should make sure that the respondent speaks English as a first language.

Summary of the Test of Word Reading Efficiency–Second Edition (TOWRE-2)

The Test of Word Reading Efficiency–Second Edition (TOWRE-2) contains two subtests: the Sight Word Efficiency (SWE) subtest, and the Phonemic Decoding Efficiency (PDE) subtest. The SWE subtest assesses the number of printed sight words that can be accurately identified and pronounced in 45 seconds. The PDE subtest measures the number of printed nonwords that can be accurately decoded (“sounded out”) in 45 seconds.

Personnel and Training Required

The Test of Word Reading Efficiency–Second Edition (TOWRE-2) can be administered by trained research assistants. Examiners should have formal training in the ethical administration, scoring, and interpretation of clinical assessments. Additionally, investigators are encouraged to have quality control procedures in place to maintain consistency across tests and among examiners. Examiners should familiarize themselves with the expected pronunciations, especially of the nonwords. Due to the speed of the word reading task, examiners may wish to record the participants’ productions and score their performance offline.

Equipment Needs

The interviewer will need the complete kit for the Test of Word Reading Efficiency–Second Edition (TOWRE-2), which includes: Examiner's Manual, Examiner Record Booklets (Forms A and B), Response to Intervention Booklets, and Word Cards for Forms A,B,C, and D. These four different versions of the test are available to facilitate retesting to monitor progress without repeating the same test version.

Definition

This measure is a test to assess the respondent's ability to read real words and nonwords rapidly and accurately.

Purpose

This measure tests a respondent's word reading accuracy and speed to provide an efficient means of monitoring word and nonword reading skills that are critical in the development of overall reading ability. Difficulty with sight word identification and nonword decoding is a key component of dyslexia.
