The in-person hands-on day is considered an orientation. Much of your time spent in person is used to observe your instructor as well as your fellow students.
Depending on the class size, attendees will be split into three or four groups and will rotate between scanning sessions and instructors. In each session, you will get a turn with your hands on the transducer.
In the first half of the day, you will get comfortable with the machine by scanning your fellow attendees (it is optional for you to participate in being scanned). In the second half of the day, you will work with actual pregnant models.
The most crucial part of your hands-on learning experience will be in the second part of your training. Which is obtaining 50-75 supervised scans by a qualified medical care professional.
