The presentation of a bill before either chamber by the recital of the caption of the bill. The Texas Constitution requires that every bill be read in each chamber on three separate days. Until a bill is finally passed, it will be in the process of a first, second, or third reading. The first reading of a bill is the point in the legislative process when the bill is referred to Committee by the appropriate presiding officer. The second reading of a bill is the first point in the process when the entire membership of a chamber has the opportunity to debate the bill and amend it by majority vote. The third reading of a bill is the next point in the process and provides a final opportunity for the entire membership of a chamber to debate a bill and for the members to offer amendments to the bill.
