What do you think about the wording every child is entitled to an adequate education?

I was speaking to a Conneticut (USA) teacher last week and she said in her state, or maybe it was her school district, every student is entitled to an adequate education. That’s how the law is worded, it is not worded that every student is entitled to an equal education.

What do you think about that?

I’m interested in both your opinions and any factual information that aids in understanding why this specific wording was used. I am also curious if this is the wording most school districts use.
