There are 3 fetters called "Self-view", "Doubt", "Grasping mere rules and rituals" to be eliminated by the Stream entry.
And there are conditions that a stream enterer must have already fulfilled, according to the Theravada Texts. (Suttas, Abhidhamma, Commentaries, Visuddhimagga)
3rd point demands very higher knowledge and awareness about the degree of the elimination of fetters/defilements he has done, at each milestone of the path.
Especially the 4th point says "if one has attained stream entry, he knows what he has done, very well."

Stream Entry (SotΔpanna) is a particular state in which someone practicing the dharma has broken the first three fetters (impediments to advancement). These are:
The cessation of mental activity for a brief moment may or may not be sufficient to break the third fetter; only you can say whether you still have doubts. It is a useful and interesting experience in any case, one which demonstrates that your practice is sound. But don't worry (or think) too much about it. An undue focus on the meaning or significance of events can lead you back into the second fetter, where you ritualize the appearance of certain states as symbols of progress.
