>> Abstract:
>> Maintaining a stable score scale over time is critical for all
>> standardized educational assessments. Traditional quality control tools
>> and approaches for assessing scale drift either require special equating
>> designs, or may be too time-consuming to be considered on a regular
>> basis with an operational test that has a short time window between an

>> are not sufficient to catch unusual testing outcomes in a timely manner.
>> This paper presents a new approach for score monitoring and assessment
>> of scale drift. It involves quality control charts, model-based
>> approaches, and time series techniques to accommodate the following
>> needs of monitoring scale scores: continuous monitoring, adjustment of
>> customary variations, identification of abrupt shifts, and assessment of
>> autocorrelation. Performance of the methodologies is evaluated using
>> manipulated data based on real responses from 71 administrations of a
>> large-scale high-stakes language assessment.
