### Our 3 Step Approach

**Step 1: Evaluation**

In our 1:1 Lesson & Private Tutoring plans, each student takes a comprehensive academic evaluation quiz which pin points strengths and weakness.

**Step 2: Study Plan**

Based on the results of the academic evaluation, our dedicated coaches develop an individualized study plan to meet each student’s needs.

**Step 3: Communication**

We keep parents in the loop by sending out a monthly personalized student progress report via email.

**Are you concerned about what we teach to your child? Don’t be**!

Our guided mathematics video lessons are aligned to public & private school curriculum. We also prepare your child for private & public school state assessments, Iowa assessments, ERB-CTP, TerraNova and Gifted & Talented programs.
