Internet testing: A natural experiment reveals test score inflation on a high-stakes, unproctored cognitive test

Computers in Human Behavior, 2009
A natural experiment is reported in which the performance of two cohorts of undergraduate students on identical tests of cognitive achievement is compared under differing conditions of proctoring and modes of administration, total N = 302. Between-subjects and within-subjects analyses reveal clear effects of test score inflation in the unproctored ...

Inflated Test Score Gains: Is the Problem Old Norms or Teaching the Test?

Educational Measurement: Issues and Practice, 1990
What explanations have been provided for spurious test score gains? Are states and districts narrowing the curriculum and teaching the test? What effect does teaching the test have on the norms themselves? What alternatives must be sought to protect the integrity of instruction and the validity of scores?

Improvement in National Test arithmetic scores at Key Stage 1: Grade inflation or better achievement?

British Educational Research Journal, 2008
The aim of the National Numeracy Strategy is to raise standards in numeracy. Strong evidence for its success has, however, been lacking: most of the available data come from performance on National Test assessments administered in schools or from Ofsted reports, and is vulnerable to suggestions of bias.

Outlier removal, sum scores, and the inflation of the type I error rate in independent samples t tests: The power of alternatives and recommendations.

Psychological Methods, 2014
In psychology, outliers are often excluded before running an independent samples t test, and data are often nonnormal because of the use of sum scores based on tests and questionnaires. This article concerns the handling of outliers in the context of independent samples t tests applied to nonnormal sum scores.

Effectiveness of non-selective evaluation test scores for predicting first-year performance in university career: a zero-inflated beta regression approach

Quality & Quantity, 2016
The background preparation of students entering the university system is checked through evaluation tests in Italy. The test is non-selective in most degree programmes, as it does not preclude the possibility of enrolling in the student’s chosen program.

Score Tests for Overdispersion in Marginalized Zero‐Inflated Poisson Regression Based on Marginalized Zero‐Inflated Generalized Poisson Model

Statistical Analysis and Data Mining: An ASA Data Science Journal
ABSTRACT A marginalized zero‐inflated Poisson (MZIP) model has been developed to allow practitioners to make direct inferences about the marginal mean of count data while accounting for the excess zeros in the data. Overdispersion is a well‐documented issue in models that include the Poisson distribution, such as the traditional zero ...

It's a Myth: High Stakes Causes Test Score Inflation (Presentation Slides)

SSRN Electronic Journal, 2017
The myth is popular among education insiders who oppose high-stakes or externally mandated tests, but is based on just two studies conducted without controls that employed an obscure definition of “high stakes”. Both studies actually involved low-stakes tests administered without security protocols.
