Tex. Education Code § 21.0412

(a) In proposing rules specifying the types of teaching certificates to be issued under this subchapter, the board shall provide for a candidate to be issued:

(1) a standard certificate if the candidate satisfies:

(A) all traditional teacher preparation requirements under Section 21.04421; or

(B) the applicable alternative teacher preparation requirements under Section 21.04423;

(2) an enhanced standard certificate if the candidate satisfies all requirements of the teacher residency preparation route established under Section 21.04422;

(3) an intern with preservice experience certificate, which expires one year after issuance unless modified by the board, if the candidate has yet to satisfy all requirements for certification for a preservice alternative teacher preparation route established under Section 21.04423(1) but has completed a sufficient number of preservice practice hours to serve as a teacher of record; and

(4) an intern certificate, which expires two years after issuance unless modified by the board, if the candidate has yet to satisfy all requirements for certification for an alternative teacher preparation route established under Section 21.04423(2) but has met all board requirements to serve as a teacher of record.

(b) Rules proposed under Subsection (a)(2) may not require a candidate to pass a pedagogy examination unless the examination tests subject-specific content appropriate for the grade level and subject area for which the candidate seeks certification.

(c) A candidate for a certification described by Subsection (a) must meet all other requirements imposed under this subchapter or board rule applicable to the candidate's certification.

(d) This section does not prohibit the board from proposing rules that provide for certifications other than the certifications described by Subsection (a), including specialized certifications and other types and classes of certifications.
