Which part of the exam focuses on the understanding of Texas rules and procedure?

The focus of Part B of the Texas Certified Shorthand Reporter (CSR) exam is specifically on understanding Texas rules and procedure. This part of the exam assesses the candidate's knowledge of procedural law, including the specific rules and regulations governing the practice of shorthand reporting in Texas. Mastery of these rules is essential for ensuring compliance during legal proceedings and maintaining the integrity of the reporting process.

In contrast, while Part A may cover other areas important to shorthand reporting, it does not specifically emphasize Texas rules and procedures. Therefore, selecting Part B is the appropriate choice for this question about understanding the relevant legal framework within Texas.
