Why Do a Developmental Screening?

Screenings ask specific questions about what your child can do. They give you a detailed look at your child’s development. Screenings are a great way to identify your child’s strengths. They can also highlight any areas where your child may need more practice or support.

  • Screening is a fun way to get to know your child
  • Screening results can help you talk to your doctor or other professionals about any concerns with your child
  • Online screenings are FREE for parents in San Mateo County, thanks to funding from First 5 San Mateo County.

How to Complete an Online Screening

Please complete both questionnaires, the General Development screening and the Social-Emotional Development screening. Together, they give you a full snapshot of your child’s motor, cognitive, language, and social-emotional skills.

There is a relationship between a child’s behavior and development. The two Ages and Stages Questionnaires can help parents better understand this connection.

“Social-emotional development is foundational—in order to be successful learners children need to get along well with others and they also need to feel good about themselves and excited about the world around them.”
