The TABE CLAS-E is intended for use with adult, non-native English speakers.
The CLAS-E proficiency test provides ESL educators and employers with student evaluation, placement, and instructional progress (pre-test form, post-test form) data in the reading, listening, writing, and speaking skill areas. CLAS-E is designed to present assessment items within workplace, community, and education contexts that will motivate adult ESL learners.
Reading, listening, writing, and speaking skills
Beginning to advanced
For each level, scored items include:
- Reading: 25 items
- Listening: 25 items
- Writing: 25 items
- Speaking: 25 items
TABE CLAS-E has both Selected Response and Constructed Response items on the test.
The CLAS-E is built on a solid foundation of research, and provides valid test results. To ensure the validity of the assessment, the test developers reviewed a wide spectrum of current ESL curricula and standards frameworks and gained input from educators in adult ESL programs. Here are highlights of the stages of test development for the assessment.
Content specialists developed items, passages, and stimuli according to test design specifications. Every item was reviewed for accuracy, appropriateness of content, context, and difficulty, as well as for relevance to the adult ESL education curricula. Then items were submitted to a diverse group of ESL education professionals for feedback on language, subject matter, and representation of various populations. Rigorous and systematic procedures were followed to reduce ethnic, racial, gender, regional, disability, and age bias.
Test developers then selected the tryout items. This phase “tests the questions” by having a large group of adult ESL students take a field-test version of the test that contains twice the number of items needed for the final tests. Thousands of adult examinees from various ESL programs across the United States took part in these tryouts.
CTB/McGraw-Hill staff analyzed data from the tryouts to determine the items’ psychometric characteristics, such as difficulty, bias, and contribution to score accuracy. Items were subjected to an empirical procedure called a Differential Item Functioning (DIF) analysis. This procedure uses quantitative methods to determine whether examinees with similar levels of ability have a similar probability of getting the item correct. This process eliminates items that include extraneous or construct-irrelevant information that make them unfairly easier or more difficult for any subgroup. In addition, the level of difficulty of items is determined by the percentage of examinees choosing the correct answer. The next step in this quantitative evaluation is the elimination of the items that do not discriminate well between the abilities of low-achieving and high-achieving students. The final forms of the test were selected by content experts and reviewed by the psychometric staff at CTB/McGraw-Hill. The primary goal was to meet content specifications, and also to eliminate bias and measurement error.
TABE CLAS-E has 2 alternate forms (A and B) and 4 levels of difficulty (1-4). The item bank for all forms and levels equals 800 items.
