How does Sylvan Learning work? Seeing results at Sylvan is as easy as 1, 2, 3! Beginning with our unique learning assessment, we work to understand your child’s needs and then create a learning plan that’s personalized just for them. That leads to better grades and happier kids (and parents)! Step 1: Complete our Sylvan Insight™ Assessment Before we can create a personal learning plan for your child, we need to know where they are on their education journey. That’s where our Sylvan Insight™ Assessment comes in. Through a combination of grade-appropriate questions and topics, we can pinpoint your child’s exact academic level. We typically assess reading, writing and math levels, along with a few additional skills. For younger children, this includes letter recognition, sounds, sight words and basic math facts. For older students, we see how prepared they are to get organized, manage their time, understand themselves as learners and take notes from a variety of sources. The results of the assessment help us understand where your child’s strengths lie, where help is needed and how they are performing compared to other students in the same grade. From there, we can begin to develop a personalized learning plan that’s tailored to your child’s exact needs and goals.

Read FAQs Step 2: Get personalized tutoring Now the fun begins. We offer tutoring by subject and grade level, so we’re ready for whatever your student needs help with. Our curriculum aligns with most school standards, and our local tutors are expert educators who understand today’s teaching methods. Your child won’t just learn new skills, though. Our goal is to help students grow in confidence and start to enjoy learning. Our tutors know how to engage and motivate students, so they’ll actually want to come to tutoring.
