What is one reason that TEKS provide for professional development?

The correct answer highlights the importance of ongoing professional development for educators, which is a central component of the Texas Essential Knowledge and Skills (TEKS). By keeping teachers informed about the latest content knowledge and effective teaching strategies, TEKS help ensure that educators are equipped to deliver high-quality instruction. This ongoing professional growth directly impacts the effectiveness of teaching and ultimately benefits the students' learning experiences.

In contrast, the other options reflect functions that are not the primary aim of TEKS. For instance, although teacher evaluations and salary determinations are important aspects of the educational system, they are driven by different frameworks and policies rather than the TEKS themselves. Similarly, the school calendar is a logistical aspect of school administration and is not related to the educational content or pedagogical strategies outlined in TEKS. Thus, the focus of TEKS on professional development is essential for fostering an environment where teachers can continuously improve their skills and adapt to new teaching challenges.
