\section{Introduction}  \label{sec:intro}  Currently most IQ data is gathered using commercially controlled tests, where their data and methods are hidden or only accessible through a paywall \cite{pearson_education_inc_wechsler_2008}. paywall.  This has a couple of downside to it. One of the downsides is each institute creating these commercially controlled tests are creating their own standard, which hinders collaboration since their work isn't transparent, for the sake of being commercially competitive. \\ This paper aims to do the opposite, by providing full transparency for data collected and methods used to get these results. As with most things, one needs to strike a balance between speed and accuracy, meaning it was assessed that an abbreviated version of ICAR had to be made, as to minimize disturbance and therefor increase chance of participation from test takers. The first challenge was to identify which items from ICAR16 should be included in ICAR5. After an abbreviated version was settled, the test was then administered to 236 pupils in the Danish school system, ranging from 6^{th} to 10^{th} grade. hhhhh
