The '''CODY Assessment''' ('''Co'''mputer aided '''Dy'''scalculia test and training) is a [diagnostic](/source/Diagnosis) screener for elementary school children from 2nd to 4th grade used to determine math weakness or [dyscalculia](/source/dyscalculia).<ref>[https://www.uni-muenster.de/CODY/ ''CODY project'' Website of the University of Münster: CODY]</ref> It also generates a detailed report evaluating each child's mathematical skills.<ref>[https://www.meistercody.com/en/page/science/ ''CODY Assessment'' Link to scientific based background of the CODY project. Retrieved 2016-02-23]</ref> It was developed in 2013 as a part of the CODY Project, which partnered [psychologist](/source/psychologist)s at the [University of Münster](/source/University_of_M%C3%BCnster) with [technology](/source/technology) experts at ''Kaasa health'', a German [software company](/source/software_industry).

== Application ==
The CODY Assessment is part of the mathematical training software Meister Cody ‒ Talasia. Children take the assessment, which creates a detailed report evaluating their math skills, when they begin the program and again 30 days later. Additionally, the CODY Project used the assessment in its research with several elementary schools in order to evaluate the mathematical skills of children before and after various instructional/ intervention methods.<ref>[https://www.uni-muenster.de/CODY/test.html University of Münster: CODY project]</ref>

== Set-up ==
The CODY Assessment takes approximately 30–40 minutes and detects four aspects: core markers (dot enumeration & magnitude comparison), number processing, calculation and working memory skills.<ref>[https://www.meistercody.com/en/page/test-and-training/ Meister Cody: CODY Assessment]</ref><ref>Kuhn, J.-T.: ''Developmental Dyscalculia. Causes, Characteristics, and Interventions.'' In: Zeitschrift für Psychologie, 2015, 223, pp 67-68.</ref> It's comprised several subtests (listed below), which evaluate both mathematical and cognitive skills:
* Reaction Time Test
* Dot enumeration
* Magnitude Comparison (symbolic and mixed)
* Transcoding
* Calculation
* Number Sets
* Number Line
* Matrix Span
* Missing Number<ref>[https://www.meistercody.com/en/page/science/ Meister Cody: Survey of subtests]</ref>

The subtests were inspired by the scientific findings of [Brian Butterworth](/source/Brian_Butterworth), who developed the background of a computer-based [screening](/source/Screening_(medicine))-test for detecting a dyscalculia.<ref>Butterworth, B.: ''Dyscalculia Screener'', 2003.</ref>

== Validation ==
[University of Münster](/source/University_of_M%C3%BCnster) validated the CODY Assessment. The [validity](/source/Validity_(logic)) and [reliability](/source/Reliability_(statistics)) of the test procedure were elaborately tested with a sample of more than 600 elementary school children from the second to fourth grade.<ref>{{Cite web |url=http://rechenguru.de/test/?lang=en |title=Rechenguru: CODY Assessment |access-date=2016-05-09 |archive-date=2016-11-07 |archive-url=https://web.archive.org/web/20161107004401/http://rechenguru.de/test/?lang=en |url-status=dead }}</ref> The [specificity](/source/Sensitivity_and_specificity) of the CODY Assessment is 81 and the [sensitivity](/source/Sensitivity_and_specificity) is 76. The Ratz-Index is 0,68, which shows a good level of reliability.<ref>[https://www.meistercody.com/en/page/science/ Meister Cody: science]</ref>
