    What ASQ Users are Saying

    “What I love about the ASQ is that it allows our staff to catch delays quickly and allows us to get our clients the early intervention programs that they sometimes need. In many cases [ASQ] helps us catch children up before they start kindergarten, therefore providing children with the start that they deserve.
