In Kelly v. State, 824 S.W.2d 568 (Tex. Crim. App. 1992), the court of criminal appeals outlined several factors that could affect a trial court's determination of reliability, including but not limited to: (1) the extent to which the underlying scientific theory and technique are accepted as valid by the relevant scientific community, if such a community can be ascertained; (2) the qualifications of the experts testifying; (3) the existence of literature supporting or rejecting the underlying scientific theory and technique; (4) the potential rate of error of the technique; (5) the availability of other experts to test and evaluate the technique; (6) the clarity with which the underlying scientific theory and technique can be explained to the court; (7) the experience and skill of the person(s) who applied the technique on the occasion in question.
