OP,
The short answer is no, because public education does not use the term "dyslexia." Officially, dyslexia is part of the category of Specific Learning Diasabilties (SLD). The only way to guarantee services is for your child to be diagnosed with a disability through a neuropsychological or psychoeducational evaluation. DCPS is supposed to provide this at no cost if parents ask.

Special education is a slippery slope into frustration in DC. Sometimes it works out fine, but there's no consistency in the quality of support. A lot depends on the principal's understanding of dyslexia and related language-based learning challenges that aren't primarily based on cognitive delays or social-emotional context like autism
In other words, there are a lot of bright people who are not on the autism spectrum, but who have challenges with reading and writing. Good educators know how to spot it early in K or 1st and adjust teaching or offer tutoring. DCPS claims to have two elementary schools that have dedicated classrooms for SLD, Garrison (more for autism) and Murch (New this year). But your child can only be placed there if they have an IEP with a diagnosed disability.
Clear as mud, right?
There are varying degrees of dyslexia and learning differences. It often coexists with ADHD, above average intelligence, and considerable creative talent. Ask your DH and other family members about what worked, or didn't, for them in school. Do a little reading about the neuroscience of reading and learning. Feel free to ask schools what their experience is with kids with LDs.
