In this presentation the challenges of implementation of (adaptive) digital testing in the Facet system in the Netherlands is discussed. In the Netherlands there is a long tradition of implementing adaptive testing in educational settings. Already since the late nineties of the last century adaptive testing was used mostly in low stakes testing. Several CATs were implemented in student monitoring systems for primary education and in the general subjects language and arithmetic in vocational education. The only nationwide implemented high stakes CAT is the WISCAT-pabo: an arithmetic test for students in the first year of primary school teacher colleges. The psychometric advantages of item based adaptive testing are obvious. For example efficiency and high measurement precision. But there are also some disadvantages such as the impossibility of reviewing items during and after the test. During the test the student is not in control of his own test; e.q . he can only navigate forward to the next item. This is one of the reasons other methods of testing, such as multistage-testing, with adaptivity not on the item level but on subtest level, has become more popular to use in high stakes testing.

A main challenge of computerized (adaptive) testing is the implementation of the item bank and the test workflow in a digital system. Since 2014 a nationwide new digital system (Facet) was introduced in the Netherlands, with connections to the digital systems of different parties based on international standards (LTI and QTI). The first nationwide tests in the Facet-system were flexible exams Dutch and arithmetic for vocational (and secondary) education, taken as item response theory-based equated linear multiple forms tests, which are administered during 5 periods in a year. Nowadays there are some implementations of different methods of (multistage) adaptive testing in the same Facet system (DTT en Acet).

In this conference, other presenters of Cito will elaborate on the psychometric characteristics of this other adaptive testing methods. In this contribution, the system architecture and interoperability of the Facet system will be explained. The emphasis is on the implementation and the problems to be solved by using this digital system in all phases of the (adaptive) testing process: item banking, test construction, designing, publication, test taking, analyzing and reporting to the student. An evaluation of the use of the system will be presented.

This study explores the use of computerized adaptive testing (CAT) to monitor the development of young children. CAT is expected to improve the measurement precision of the instrument. We do two simulation studies - one with real data and one with simulated data - to evaluate the usefulness of CAT. It is shown that CAT selects developmental indicators that maximally match the individual child, so that all children can be measured to the same precision.}, keywords = {*Child Development, *Models, Statistical, Child, Preschool, Diagnosis, Computer-Assisted/*statistics \& numerical data, Humans, Netherlands}, isbn = {0277-6715 (Print)}, author = {Jacobusse, G. and Buuren, S.} } @booklet {201, title = {The AMC Linear Disability Score project in a population requiring residential care: psychometric properties}, journal = {Health and Quality of Life Outcomes}, volume = {2}, year = {2004}, note = {Holman, RebeccaLindeboom, RobertVermeulen, Marinusde Haan, Rob JResearch Support, Non-U.S. Gov{\textquoteright}tValidation StudiesEnglandHealth and quality of life outcomesHealth Qual Life Outcomes. 2004 Aug 3;2:42.}, month = {Aug 3}, pages = {42}, edition = {2004/08/05}, abstract = {BACKGROUND: Currently there is a lot of interest in the flexible framework offered by item banks for measuring patient relevant outcomes, including functional status. However, there are few item banks, which have been developed to quantify functional status, as expressed by the ability to perform activities of daily life. METHOD: This paper examines the psychometric properties of the AMC Linear Disability Score (ALDS) project item bank using an item response theory model and full information factor analysis. Data were collected from 555 respondents on a total of 160 items. RESULTS: Following the analysis, 79 items remained in the item bank. The remaining 81 items were excluded because of: difficulties in presentation (1 item); low levels of variation in response pattern (28 items); significant differences in measurement characteristics for males and females or for respondents under or over 85 years old (26 items); or lack of model fit to the data at item level (26 items). CONCLUSIONS: It is conceivable that the item bank will have different measurement characteristics for other patient or demographic populations. However, these results indicate that the ALDS item bank has sound psychometric properties for respondents in residential care settings and could form a stable base for measuring functional status in a range of situations, including the implementation of computerised adaptive testing of functional status.}, keywords = {*Disability Evaluation, *Health Status Indicators, Activities of Daily Living/*classification, Adult, Aged, Aged, 80 and over, Data Collection/methods, Female, Humans, Logistic Models, Male, Middle Aged, Netherlands, Pilot Projects, Probability, Psychometrics/*instrumentation, Questionnaires/standards, Residential Facilities/*utilization, Severity of Illness Index}, isbn = {1477-7525 (Electronic)1477-7525 (Linking)}, author = {Holman, R. and Lindeboom, R. and Vermeulen, M. and de Haan, R.
