This article describes and reviews the "Test of Early Communication and Emerging Language" (TECEL; Huer & Miller, 2011). The test was constructed to assess infants' and toddlers' earliest communication and language abilities. The TECEL is a revision of the Nonspeech Test for Receptive/ Expressive Language (NST; Huer, 1983, 1988). The examiner's manual suggests that the instrument can be used for a wide variety of purposes, such as evaluating communication and language strengths and weakness for young children, predicting future language development, and designing intervention plans, and can be used as a research instrument for exploring young children's communication and language development. The instrument is based on two theories of communication and language development. First, necessary for the development of young children's communication and language abilities is the context of daily social interactions attended and facilitated by adults (e.g., parents or caregivers). Overall, the TECEL test materials and stimuli are user-friendly and developmentally appropriate. The testing booklet is well organized with detailed information that describes administration procedures. The 70-page Examiner's Manuel is brief but contains explicit headings and adequate information in each section. The uniqueness of the TECEL is its companion Informal Assessment and Intervention Plan, which provides the framework for examiners to design intervention plans for children based on their test performance. The intervention plan strengthens the TECEL's application in screening, placement, and diagnostics. Three types of validity were investigated and reported in the TECEL examiner's manual: content validity, criterion validity, and construct validity. Overall, the TECEL, is a brief and user-friendly instrument with evidence of high reliability and strong validity, measures communication and emerging language ability of infants and toddlers.
