The Origins of ETS Work with Young People English proficiency is an increasingly important skill for students and young adults worldwide - Expanding access to educational, personal and professional opportunities EFL instruction is beginning at earlier ages English-medium instructional environments take many forms internationally: - Public and private schools in English-dominant countries - International schools in non English-dominant countries - Schools in any country using bilingual or CLIL approaches - Vocational schools Responds to aspirations of students as they attain English-language proficiency
How ETS Develops Quality Tests
Overview Before discussing how ETS develops quality tests, I will discuss what we mean by quality in testing. Then I will discuss the major steps in test development that are required to create a high quality test.
What Is a Quality Test? A quality test must be Reliable Valid Fair Practical
Reliable A test is only a sample. The items are a sample of all the items that could be asked. The time of testing is a sample of all the times that the test could be given. The person scoring the essay is a sample of all possible scorers.
Reliability Is Consistency If test takers knowledge is constant, how consistent would scores be if samples changed and parallel items were used? The test was taken on a different day? Different judges were used for scoring essays? The higher the reliability, the more consistent the scores will be.
Factors That Determine Reliability All other things being equal, the more independently scored items, the higher the reliability the more the items correlate with each other, the higher the reliability the greater the variability of scores, the higher the reliability
Validity Most important indicator of test quality Extent to which inferences based on test scores are appropriate & supported by evidence Requires evidence to support the use of the test for the intended purpose
Evidence of Validity Qualifications of test designers Process used to develop test Qualifications of item writers and reviewers Statistical indicators of item quality and fairness Expert judgments of test content
Evidence of Validity Match of items to content standards Relations among parts of the test Relations of scores with other variables Results fit with theories Claims for use of test are met Good consequences
Fairness = Validity for All Fairness is an aspect of validity. Tests that show valid differences across groups are fair. Tests that cause invalid differences across groups are not fair.
Practicality Tests must be affordable in dollar costs and in time used. Scores must be understandable & helpful to score-users. Items must be acceptable to diverse constituencies. Every test is a compromise among competing demands.
Major Steps in Test Development 1) Make Initial Plan for Test 2) Involve External Experts 3) Write/Review Items 4) Pretest Items (Whenever Possible) 5)Review Data & Revise Items 6)Assemble Final Test
Major Steps (continued) 7) Administer Tests 8) Checks Before Scoring 9) Scaling & Equating 10) Test Analyses 11) Report Scores 12) Begin Planning for Next Form
1) Plan Test Purpose What is test used for? What decisions made on the basis of the scores? Population What are characteristics of test takers? Construct Content & skills
Plan Test What constraints on test design? Time, cost, format, scoring, etc. Initial plan for test development work Major tasks, schedule, staff Evidence-Centered Design What claims about test takers? What evidence supports claims? What tasks provide evidence?
2) Involve External Experts Diverse (demographic, geographic, institutional, point of view) external contributors required in test design, item writing and reviewing. Diverse experts help establish acceptability, validity and fairness.
Tasks of External Experts Set/approve test specifications What content to measure? What skills to measure? What statistical properties? Write and review test items Select items for final form
3) Write/Review items Make item-writing assignments Write items to meet specifications Write overage for attrition Internal & external reviews & revisions At least 2 independent content reviews per item Separate editorial review Separate fairness review
4) Pretest When possible, try out items before operational use. Gives information to : Identify problem items (ambiguous, wrong difficulty, poor discrimination. For MC: no key, multiple keys, bad distracter) Pick most appropriate items to meet specifications Estimate final form characteristics from item data
Use Differential Item Functioning (DIF) DIF = statistical measure of how matched people in different groups perform on an item. DIF helps spot items that may be unfair. DIF is NOT proof of bias.
Uses of DIF If data available, tests assembled with low DIF items. If no data at assembly, DIF calculated after administration. High DIF items reviewed and removed before test is scored, if judged unfair. External people involved in reviews.
5) Review Data & Revise Items Review test items based on data Ensure accuracy, clarity Appropriate difficulty Acceptable discrimination Revise or drop problem items Write new items if necessary to meet specifications
6) Assemble Final Test Choose set of items from pool according to specifications Perform test reviews Meet content, skill, & statistical specifications Check for overlap, cueing of keys Correctness of keys
7) Test Administration Print or format for computer Quality control checks Ship securely Administer test Acceptable conditions (space, comfort, light, temperature) Security (copying, impersonation, prior knowledge)
8) Checks Before Scoring Investigate complaints & reports Preliminary Item Analysis (PIA) Identify problem items based on statistics (too hard, too easy, poor discrimination, change from pretest) Review items to decide if keep in test or drop before scoring DIF, if not done previously
Checks Before Scoring Check for anomalies (sudden drops or increases in scores) that may indicate problems
9) Scaling & Equating Raw scores are number right or percent right on a particular test form. 50% right on a hard test form may take more knowledge & skill than 60% right on an easy test form. Raw scores mean different things on different test forms. ETS very rarely reports raw scores
Scaling & Equating Scaling is arbitrary range of numbers used to report scores. e.g., for SAT, for PPST. Equating is a statistical adjustment for differences in the difficulty of different forms of the same test. Equating allows us to treat the scores on different forms of a test as though they meant the same thing.
Scaling & Equating If a form happens to be a little harder than the others, it will take fewer raw score points to reach a particular scale score point. If a form happens to be a little easier than the others, it will take more raw score points to reach a particular scale score point. Scaled scores, after equating, mean the same on each form
10) Test Analyses Analysis of final form characteristics. Distribution of item difficulty & discrimination Reliability Speededness Did test meet content & statistical specifications? If not, where were problems?
11) Report Scores Explain what scores mean so scores are understandable to test users Indicate Standard Error of Measurement on score report
12) Plan Next Form What was learned from this administration to make the next administration of the test better? What has to change for next form?

The TOEIC Bridge Test
What is the TOEIC Bridge Test? A test to measure the emerging competencies of beginning learners of English A tool to help language learners focus on areas for improvement
Why use the TOEIC Bridge Test? To measure beginner English proficiency To motivate English Language Learners To set language learning goals
How is the TOEIC Bridge Test different from the TOEIC ® Listening and Reading Test? The TOEIC Bridge test takes only one hour. The TOEIC ® test takes two hours. There are 100 questions in the TOEIC Bridge test, 200 in the TOEIC ® test. The TOEIC Bridge has only five parts, the TOEIC ® test has seven parts. There is more time between questions in the TOEIC Bridge test. In the TOEIC Bridge test, the speakers speak more slowly.
Differences (Continued) TOEIC Bridge test questions are easier. TOEIC Bridge test questions cover more general topics. The scaled score range on the TOEIC Bridge is from 20 to 180; on the TOEIC ® test, scores are on a scale of 10 to 990. The TOEIC Bridge test is a low-stakes test; the TOEIC ® test is a high-stakes test.
Test Format Two sections: Section I: Listening Comprehension – Candidates listen to a variety of statements, questions, short conversations, and short talks, and answer 50 questions.(tape mediated) Three Parts: Photo-based (15 questions) Question-Answer (20 questions) Conversations and Short Talks Section II: Reading Comprehension – Candidates read single sentences as well as texts and answer 50 comprehension questions. Two Parts: Incomplete sentences (30 questions) Reading Comprehension (20 questions)
TOEIC Bridge Content Areas Animals Basic objects Clothing Dates/days/time Entertainment Family members Food/dining out Games Health Housing/residence Measurement Money Months Music Numbers Recreation/hobbies School subjects Shopping Sports Travel/transportation Weather Work
Scoring Total scores range from Listening and Reading subscores range from 10 – 90 Test administration time is approximately 1.5 hours Test scoring – (under operational conditions) hours in most locations
The scores are based on the number of correct responses. The correct responses in each section (Listening and Reading) are converted to a score scale. The range of the scale is from 10 – 90 for each section. Summing the scores of the sections produces a total scaled score. The range of the total score is then 20 – 180.
CEFR Ratings The TOEIC Bridge test ranges from the A1 level to the B1 level.
