One way to prepare for your call is to create a script and use it to practice. You don‘t need to follow the script word for word, but having something prepared will help you stick to the point and get the information you need. A script can also be helpful in case you are nervous or are worried about what to say during the call.
When calling a business, use a professional voice, not a conversational tone that you might use when talking to your friends on the phone. Unlike a friend, a potential business host has never met you. When you call to introduce yourself, you are making an important first impression.
Example Script
Hello, May I speak with [Name of Your Business Host], please?
When your business host comes to the phone, say the following:
Hello, my name is [Your Name]. I am calling from [Your High School] to confirm my job shadow on [Day of the Week], [Month and Date] from [Start Time] to [End Time].
Is there anything else I need to know upon arrival? (Confirm attire, parking, etc.)
Thank you. I look forward to seeing you soon. Goodbye.
