Model answer (CLB 7)

Subject: Appointment Reschedule Request — Monday, June 9 at 2:00 p.m.

Dear Sunridge Dental Team,

I am writing to request a reschedule of my appointment on Monday, June 9 at 2:00 p.m. Unfortunately, a mandatory work meeting has just been scheduled for the same time, and I am unable to miss it.

I sincerely apologize for the short notice and understand that this may be inconvenient. I would be grateful if I could reschedule to later in the week. I am available on Wednesday or Thursday afternoon after 3:00 p.m., or any time on Friday.

Thank you for your understanding, and I hope to find a time that works for both of us.

Regards, Yuki Tanaka Patient ID: 88-4401


Why this scores CLB 7

CLB CriterionWhat this response does well
PurposeClear reschedule request with reason
DetailSpecific date, time, reason, patient ID, alternative availability
OrganizationProblem → apology → request → availability → close
TonePolite, acknowledges inconvenience to the other party
Vocabulary”mandatory,” “sincerely apologize,” “inconvenient”
GrammarAccurate use of conditionals and polite requests

Common mistakes at CLB 5–6

Weak versionWhy it loses marks
”I can’t come Monday. Call me.”Rude and incomplete
No apologyThe prompt says “apologizing for short notice” — this is required
Not offering alternative timesMakes the office do extra work — a professional always offers availability
”I have a meeting” (no further context)Adding “mandatory” signals you cannot change it — important for credibility

Examiner tip

Rescheduling emails seem simple but many test-takers lose marks by omitting the apology or forgetting to suggest alternative times. Both are explicitly in the prompt. Read the prompt carefully and treat each instruction as a required element. Missing even one drops your completeness score by at least one CLB level.
