Why are we here? CEM aims to • Create the best assessments in the world • Empower teachers with information for self-evaluation • Promote evidence-based practices and policies, based on scientific evaluation To help educators improve educational outcomes measurably
CEM activity • The largest educational research unit in a UK university • 1.1 million assessments are taken each year • More than 50% of UK secondary schools use one or more CEM system • CEM systems used in over 50 countries • Largest provider of computerised adaptive tests outside US
Outline • Assessment is the most powerful lever we have • Quality matters • Technology can make assessment • Efficient • Diagnostic • Embedded • Fun • Valid • Standardised • Secure • Informative
Good Assessment • Makes learning visible • Makes us focus on learning • Allows us to evaluate • What students do and don’t know • Against appropriate norms • Effectiveness of teaching • Allows us to diagnose • Specific learning needs

Definition of a grade ‘An inadequate report of an inaccurate judgment by a biased and variable judge of the extent to which a student has attained an undefined level of mastery of an unknown proportion of an indefinite material.’ Dressell (1983)
Would you let this test into your classroom? Does the test discriminate adequately between different levels of performance? How well do the test scores predict later performance? How long does the test (or each element of it) take each student? How clearly defined are the acceptable interpretations and uses of test scores? Do repeated administrations of the test give consistent results? Do the responses have to be marked? How much time is needed for this? How well do the test scores correlate with other measures of the same thing? What does the test claim to measure? Do the test items look appropriate? How well does the measure correspond with measures of the same and related constructs, using the same and other methods of assessment? Do test scores reflect factors other than the intended construct (such as gender, social class, race/ethinicity)?
Computer Adaptive Testing • Right answers harder questionsWrong answers easier questions • Can give same information in half the time • More accurate at the extremes • More pleasanttesting experience • Need access tocomputers • Development costshigher
In the future, technology allows • Teachers to author, share and evaluate test items • ‘Home-made’ tests with standardised norms • Adaptive presentation • Automatic marking of complex responses • Platforms for efficient and quality-controlled human judgement (marking) • Cheat detection • Sophisticated feedback to students and teachers
