Final answer:
After failing the appraiser licensing exam three times in Texas, the applicant must take additional qualifying education before attempting the exam again to ensure they are adequately prepared for successful licensure.
Step-by-step explanation:
If an applicant for an appraiser credential in Texas fails the licensing exam three times, the correct step to take next is: 4) The applicant must take additional qualifying education before taking the exam again. After failing the licensure exam three times, the Texas Appraiser Licensing and Certification Board (TALCB) requires applicants to complete additional educational coursework. This is often to ensure that the applicant has the necessary knowledge and competencies to pass the exam on their next attempt. This rule is designed to maintain the professional standard of appraisal practice in Texas and ensure that all licensed appraisers are well-prepared to perform their duties. The other options provided are incorrect: 1) There is no one-year waiting period required, 3) An applicant is not permanently barred from receiving an appraisal credential, and 2) Taking an exam in another state with an 'easier' exam does not guarantee a credential in Texas.
