Answers to frequently asked questions
We love to hear from you!
Each one of our schools has unique needs. We want to hear directly from you about your programs, community, and expectations...
This free 30-minute consultation is held via Zoom. We will dive into understanding your school's needs and preferences, but we also want you to get to know us. We'll answer all of your questions and provide you with details about our services, teacher qualifications, pricing, scheduling options, data tracking, and more.
The LD Expert strives for professionalism in all of our operations. Our School-Based Services Contracts can be signed digitally.
At any time, you are permitted to make changes to your schedule or decide that our services are not a good fit for your school. Even though your contract is signed for a year, we ask for 30-days notice to terminate the contract without any early termination fees.
At LD Expert, we pride ourselves on being fexible and accommodating with scheduling. Our team of teachers can see students during the school day according to your unique bell schedule, after school, or in the evenings. We will work with you to find days and times that fit your school's needs.
For Wilson Students Only:
The Wilson Reading System has a great initial assessment called the Wilson Assessment of Decoding and Encoding (WADE). This assessment takes about 30-45 minutes, and is completed virtually. Your student will just need access to a writing utensil and printer (to print the pages for writing on prior to our scheduled meeting time).
After the assessment is complete, we will write up a report summarizing the results and share it with you. This assessment will guide us on choosing the appropriate starting point in the program based on your student's individual needs.
Once we have received your signed contract, lessons can offically begin! Teachers will send families, students, and teachers an introduction email that includes instructions about how to log into their Zoom Meeting Room.
It is a good idea to have an adult present or accessible the first couple sessions, but students catch on very quickly and are typically able to log-in without assistance after the first couple sessions.
LD Expert utalizes an online platform for billing, scheduling, data tracking, and communication. Families, school administrators and/or teachers will be given login information to access student data at any point in time. The data would include lesson summaries, encoding errors, decoding errors, and assessment results.
Additionally, after each lesson, our teachers write-up a summary of the lesson and it can be emailed to parents, teachers, or adminsitrators directly with a single click!
