Answer > decision trees accuracy rate/level (date: 2010-06-18)

The simplest way is to compute misclassification error from the confusion matrix. Confusion matrix is a tabular comparison between the count of true labels and the predicted labels. Misclassification error is computed based on count of the error of classification compare to total cases. Check my Discriminant Analysis tutorial for the numerical example.
