Progress in the understanding of quantum critical properties of itinerantelectrons has been hindered by the lack of effective models which are amenableto controlled analytical and numerically exact calculations. Here we establishthat the disorder driven semimetal to metal quantum phase transition of threedimensional massless Dirac fermions could serve as a paradigmatic toy model forstudying itinerant quantum criticality, which is solved in this work by exactnumerical and approximate field theoretic calculations. As a result, weestablish the robust existence of a non-Gaussian universality class, and alsoconstruct the relevant low energy effective field theory that could guide theunderstanding of quantum critical scaling for many strange metals. Using thekernel polynomial method (KPM), we provide numerical results for the calculateddynamical exponent ($z$) and correlation length exponent ($\nu$) for thedisorder-driven semimetal (SM) to diffusive metal (DM) quantum phase transitionat the Dirac point for several types of disorder, establishing its universalnature and obtaining the numerical scaling functions in agreement with ourfield theoretical analysis.
