Ms. Thompson is a new seventh-grade teacher. Pressed for time, she administers a test she finds in the files left by her predecessor. When students uniformly perform poorly, she realizes that the test assesses content she did not teach. She decides against administering another test and records the students' grades in her grade book. Her testing error comes to light when the parents of several students complain to the school leader about their children's grades. Which of the following is the school leader's most appropriate action for improving Ms. Thompson's practice?
a) Providing the teacher with immediate targeted training on professional ethics
b) Scheduling a meeting with the parents to discuss the grading issue
c) Ignoring the complaints since the test was from the previous teacher
d) Reprimanding Ms. Thompson for not preparing her own test
