The product of decades of research by Jane Squires, Diane Bricker, and their colleagues, ASQ® answers the need for an affordable, reliable, way to screen children in the critical early years and identify potential delays. This trailblazing screener is the first to have parents complete the questionnaires—which makes results more accurate and makes screening more efficient and economical.

Today, ASQ is the most widely used and respected developmental screener in the world. More than a million questionnaires are completed every year, and the third edition, ASQ®-3, has been translated into more than 30 languages.  New ASQ products have addressed users’ evolving needs, including ASQ Online and the dedicated social-emotional screener ASQ®:SE-2.
