34 Tex. Admin. Code § 67.69
The rules of evidence as applied on nonjury civil cases in the district courts of this state shall be followed. Irrelevant, immaterial, or unduly repetitious evidence shall be excluded. When necessary to ascertain facts not reasonably susceptible of proof under those rules, evidence not admissible under them may be admitted (except where precluded by statute) if it is of a type commonly relied upon by reasonably prudent men in the conduct of their affairs. The rules of privilege recognized by law shall be effective in board proceedings. Objections to evidentiary offers may be made and shall be noted in the records. No evidence will be admissible in a proceeding if it is beyond the scope of the notices of issues and matters asserted in the contested case.
