The invention relates to a data accuracy judgment method and device, a terminal and a computer readable storage medium. The data accuracy judgment method comprises the steps of acquiring a data set, wherein the data set is composed of at least one form; determining the type of the form; determining quality judgment parameters of the form according to the type of the form, wherein the quality judgment parameters corresponding to the type of the form are prestored in a quality judgment parameter database; calculating judgment characteristic parameters of the data set according to the quality judgment parameters of the form, wherein the judgment characteristic parameters are used for judging the accuracy of data in the data set; and judging the accuracy of the data set according to the judgment characteristic parameters. The data accuracy judgment method solves the problems that the data accuracy judgment efficiency is reduced because the data is repeatedly calculated due to the data processing process of the data set in the prior art, different judgment results are obtained in the process of evaluating the data accuracy by using various methods, mutual interference of multiple judgment results is possibly caused, and the final data judgment accuracy is affected.
