Both tutoring and after school programs are certainly useful ways to help a child who has a specific, identifiable academic weakness. First, you want to answer a couple of questions for yourself.
What is the goal of the tutoring/enrichment you seek for your child? Are you looking for an improvement in grades? For the child to become more engaged as a reader/writer? Make sure you come to any potential provider with as clear a picture as you can of what you hope to achieve with their help, including a clear idea of the timeline you have in mind for improvement.
What is your budget? Tutoring, though often highly effective, can also be extremely expensive, and the best after-school and enrichment programs aren't cheap either. Have a clear idea what you can reasonably spend before you start your search.
Once you've answered those questions, I'd advise trying to find tutors, tutoring centers, and enrichment programs that are in your price range. Our search will allow you to find reading tutors near you; you should talk to potential tutors about how they would approach the problems your child has, their availability, etc. A good tutor will work with you to build a plan and will set clear expectations of how the process will move forward.
Many tutoring centers offer diagnostic tests that will isolate your child's particular problem areas, and will build a practice plan around those problem areas; some tutors have the tools to perform a similar analysis.
As for tutoring versus enrichment, consider our article on Tutoring vs. Enrichment Classes: Which One is Better?.
If you want to share more specifics on your child's particular problems (including grade level and the specific problems you're hoping to tackle), I'd be happy to try to get more specific in my advice.
