If you have a child starting Kindergarten the Fall of 2019 the application is due in December of 2018. Start drilling him or her on their alphabet, sounds, colors, shapes, now because they will have to take the Vanguard test January or February of 2019. That's only one year away! My best advice on this. Buy those workbooks at Walgreens and CVS in the book/magazine area. They were great for teaching the kids the basics and inexpensive.

The Kinkaid EMSI program- a well kept secret.
