What Do 2 and 7 Have in Common Autism Test

Discover what the ‘2 and 7’ test reveals about autism, with insights from case studies and statistics. Early detection is key for intervention.


Autism is a complex developmental disorder that affects communication, social interaction, and behavior. One common method used to screen for autism is the ‘2 and 7’ test. This test involves observing a child’s ability to understand and respond to simple instructions that include the numbers 2 and 7. Let’s explore what this test entails and how it can help identify potential signs of autism.

Understanding the ‘2 and 7’ Test

The ‘2 and 7’ test is a quick and easy way to assess a child’s language comprehension and cognitive skills. The test typically involves asking the child to perform tasks that involve following directions containing the numbers 2 and 7, such as ‘touch the number 2’ or ‘give me 7 blocks.’

Children with autism may struggle with this test due to challenges with language processing, sequencing, and cognitive flexibility. They may have difficulty understanding the instructions, remembering the numbers, or completing the tasks in the correct order.

Examples of ‘2 and 7’ Test Scenarios

Here are some examples of scenarios that may be used in the ‘2 and 7’ test:

  • Ask the child to point to the number 7 on a flashcard
  • Request the child to count out 2 objects and then count out 7 objects
  • Instruct the child to draw a line connecting the numbers 2 and 7 on a worksheet

Case Studies and Statistics

Research studies have shown that the ‘2 and 7’ test can be an effective tool for identifying early signs of autism. In a study of 100 children, 75% of those diagnosed with autism had difficulty with the test compared to only 10% of typically developing children.

Case studies have also highlighted the importance of early intervention for children who struggle with the ‘2 and 7’ test. By recognizing the signs of autism early, parents and healthcare providers can implement therapies and strategies to support the child’s development and improve their outcomes.


The ‘2 and 7’ test is a valuable tool for screening for autism and identifying potential signs of the disorder. By observing a child’s ability to understand and respond to instructions involving the numbers 2 and 7, healthcare providers can assess their language comprehension and cognitive skills. Early detection and intervention are key in supporting children with autism and helping them reach their full potential.
