7 Best Online Tutoring Websites of 2021

Tutoring Services

Online tutoring is a great way to keep your child’s grades up from the comfort of your own home. You can stay on your regular schedule since you don’t have to pick them up whenever they finish, and it’s also usually more affordable and convenient compared to in-person tutoring. And now, during the Covid-19 pandemic, online tutoring can help keep your child safe by reducing the risk of exposure. 

You may be wondering if online tutoring is actually as effective as in-person learning. The answer often depends on the tutor, and online tutoring services provide plenty of tutors to choose from—especially compared to in-person options. This makes it not only easy to find a tutor, but also to change tutors if you decide to look for a better fit. 

Research also shows that online tutoring can be very effective: One study found that online tutoring led to significant improvements in academic and social-emotional outcomes, especially when the tutor incorporated a shared whiteboard and video calls. Another study showed that students who interacted online with their tutors performed better than students who were limited to in-person interactions with the same tutors. 

However, not all online tutoring services are created equally. To find the most effective tutoring program for your child’s unique needs, it’s crucial to understand what each of them offers—so we put together this list to help you learn about your available options.
