The Classroom Observation Schedule to Measure Intentional Communication (COSMIC): an observational measure of the intentional communication of children with autism in an unstructured classroom setting.

Pasco et al. (2008) built a new classroom tool called COSMIC. It counts how often autistic kids use intentional communication during regular class time.

The team tested COSMIC with children in real classrooms. They checked if different observers scored the same acts and if the scores matched gold-standard tests like ADOS-G.

COSMIC showed strong inter-rater reliability. Two people watching the same child gave nearly the same scores.

The tool also predicted later language skills. Kids who scored high on COSMIC tended to have better communication months later.

Goldstein (2002) and Cui et al. (2023) list many ways to teach communication to autistic children. COSMIC gives you a quick way to see if those lessons actually show up during everyday school routines.

Porter et al. (2008) created the ToM Storybooks to measure theory of mind. COSMIC is its classroom cousin, but it tracks expressive acts instead of hidden thoughts.

Gunn et al. (2021) built COSTI to watch teachers. COSMIC flips the lens to watch students. Both tools are free, quick, and built for busy general-ed rooms.

You no longer need to pull kids out for long tests to see if they are gaining intentional communication. With a short COSMIC sweep you can spot growth, set goals, and show administrators real numbers from real class time. Try it before and after any communication intervention to prove your treatment worked in the setting that matters most.
