Recent literature in the field of L2 vocabulary assessment has advocated for the development of written receptive vocabulary tests such as Vocabulary Levels Tests (VLTs) that use: (a) meaning-recall item formats, (b) a minimum of 40 item counts per 1,000-frequency band to improve level estimates, and (c) lemmas (not word-families) as the lexical…

Objective: This study was designed to produce a new parent-report measure, the Diagnostic Receptive Expressive Assessment of Mandarin-Infant Toddler Assessment of Communication and Language (DREAM-IT) in order to provide norms for the developmental skills of children aged 0-36 months in four areas: expressive language, receptive language,…

The current study describes the development and validation of a novel scale (BILEX) designed to assess young bilingual children's receptive vocabulary in both languages, their conceptual vocabulary, and translational equivalents. BILEX was developed to facilitate the assessment of vocabulary size for both of the children's languages within one…

Research Findings: The aim of this study was to construct and validate "English Picture Vocabulary Test (EPVT)" that aimed to assess the very young learners' (VYLs) receptive and expressive vocabulary knowledge for specific content areas in English as a foreign language (EFL). In this context, EPVT was created in several stages. One of…

Recently, research in second language acquisition has seen an increased attention on low-educated low-literate (LESLLA) learners. However, few of the existing instruments to measure L2 proficiency have been validated for use with this population. In this paper, we examine how adult L2 learners with diverging educational backgrounds perform on and…

Background: The aims of the current study were to adapt a version of the MET for people with intellectual disabilities and assess its ecological and construct validity. Material and Methods: Using a correlational design, 40 participants with intellectual disabilities were invited to complete a battery of neuropsychological assessments and the…

This article describes the development and validation of the new CATSS (Computer Adaptive Test of Size and Strength), which measures vocabulary knowledge in four modalities -- productive recall, receptive recall, productive recognition, and receptive recognition. In the first part of the paper we present the assumptions that underlie the test --…

The American Sign Language Comprehension Test (ASL-CT) is a 30-item multiple-choice test that measures ASL receptive skills and is administered through a website. This article describes the development and psychometric properties of the test based on a sample of 80 college students including deaf native signers, hearing native signers, deaf…

This article presents evidence for a validity argument on the ACTFL Assessment of Performance Toward Proficiency in Languages (AAPPL) tests (Interpersonal Listening/Speaking, Presentational Writing, Interpretive Listening, and Interpretive Reading) by summarizing an analysis of the 2014 test data from examinations administered in three languages…

This article describes the development and validation of the Developmental Snapshot, a 52-item parent questionnaire on child language and vocal communication development that can be administered monthly and scored automatically.

Joint attention (JA), the ability to share attention to an object or event with another person, is one of the earliest identified deficits in autism spectrum disorders (ASD) and directly influences language and social development. There are several effective assessments of JA for young children (e.g., Mundy et al., 2003), but none are appropriate…

This article focuses on the development of a Literacy Assessment Battery for the diagnosis of Maltese children with specific learning difficulties. It forms part of a wider research study involving testing of 549 children in Malta as well as standardisation of the tool. Results of the children's performance and psychometric validation go beyond…

Purpose: To scale language milestones in a group of 527 children to provide an instrument for screening language development. Procedure: The questionnaire regarding these milestones was completed by parental report. It was evaluated whether the scaled milestones satisfied the assumptions of the Mokken item response model. Results: The scalability…

The objective of this study was to develop a highly reliable instrument for primary grade students which was relatively culture free and could accurately identify each child's dominant language. In addition, it should provide normative data regarding the child's fluency in his two most predominant languages. This test, known as the Test of…
