In the first four years of running, the LHC has delivered a wealth of new data that is now being analysed. The two multi-purpose detectors, ATLAS and CMS, have performed many searches for new physics but theorists are eager to test their own particular model. We present the latest developments to the program CheckMATE (Check Models At Terascale Energies) that helps to automate this procedure so that new theories can easily be checked against the latest results. The backbone of CheckMATE is a library of over 50 LHC analyses that new physics models can be tested against. The user only needs to provide a model in SLHA format and CheckMATE will automatically decide if the model is ruled out or not. In addition, if new physics begins to appear, CheckMATE offers the possibility to quickly determine the model that best fits the data. Finally, a novel technique using kinematic transformations of existing events is presented that promises to speed up the determination of model best fit points by orders of magnitude.
