I have worked for two tutoring companies. For one, I was paid $25/hour. I was given access to the child's testing results (tests done by the company) and had to interpret the results myself, provide my own materials, etc.
The other was Sylvan. I was paid considerably less ($8.50/hour) and worked as many as 4 to 1 instead of 1 to 1 (as with the other company). One the upside, all the kids met you at Sylvan, you didn't have to interpret the testing results and figure out what the child needed to be successful, and there was a full curriculum worked out for the instructors.
It should be noted that Sylvan and other similar companies are not "tutors." These companies test your child first to determine where s/he might have a deficiency. The testing will determine what grade level your child is working on, and will only work on skill strands that your child needs help with.
In other words, it is an individualized program that is geared towards figuring out what necessary foundational skills your child is missing and going back and filling in those blanks and building up to the appropriate grave level. With this program, your child should show improvement -- it may be gradual, but the key is that the company is trying to go back and fill in gaps in the child's learning which can occur for many reasons -- didn't get it the first time, was absent when all or part of that lesson was taught, etc. For some things, if you don't acquire the appropriate foundation, anything that is built upon that foundation will be weak.
Tutors, on the other hand, generally take the child's current coursework, books, etc., and try to help bring the child up to speed on the current work. There is no going back and trying to fill in foundational skills unless it is determined during the course of tutoring that you aren't getting C because you don't understand A and B, and you need know A and B to get C.
(Note that I am not necessarily advocating for Sylvan and other such companies. I just want to make sure the process is understood. It should also be noted that, should you choose to go with Sylvan, when I worked for them, you signed a contract for
36 hours. Our director (franchise...) would have parents sign the contract for at least 42. At that point, (which, again, should be 36 hours of instruction, regardless of whether it's an hour a day 4 days a week or an hour one day every other week) the child is supposed to be reassessed for progress and the curriculum changed, if necessary and if you want your child to continue with the program. Our director would push 42 instead of 36 so he could get more money out of the clients. Maybe because he was a franchise he could do what he wanted...and maybe someone finally complained, and that's why he's not a franchise anymore...)
A PP mentioned that Sylvan boosts confidence. I would agree with this. Sylvan works on a token system. As you successfully complete assignments, the child earns tokens which they can spend in the store.
Some other things to note:
Sylvan has a 100% free reading program called Book Adventure. (
http://www.bookadventure.com) You can sign up your child for this program. Most of the Book Adventure books are Accelerated Reader books. I recommend this site to my students' parents. It has quizzes that are similar to the AR quizzes. Last time I was on it, you could test on a book 3 times without passing before it locks you out of the quiz. For AR, you can only take it once. You can sign up for Book Adventure, have your child take the quiz, and get an idea of whether or not your child is ready to take the AR quiz at school. Again...similar tests -- they do not use the same questions, but it does ask questions about what was read and such just like AR.
Sylvan also does "classes" like Study Skills, ACT Prep, and has a credit recovery program (aka Summer School). I don't know how the cost for credit recovery compares to the cost through the school system, but if your child is in that situation in which s/he needs to make up a class s/he failed, you might want to ask about this.
