## What is STAC Unlimited?

The Standardized Touchscreen Assessment of Cognition (STAC) is an automated screening tool that allows therapists and other health-care providers to obtain cursory information about an individual’s cognitive function.
The STAC assesses cognitive and linguistic functions and enables the examiner to receive both quantitative and qualitative information about a person's cognitive abilities.

The STAC is a self-administered, automated assessment making the administration consistent from session to session eliminating examiner bias with serial administrations of the test. The scoring is automated, however qualitative information from each patient is determined based on time elapsed during timed subtests, pattern of responses and ability to process sub-test instructions. A full report is immediately accessible following the test administration, and can be emailed directly to the clinician.
Ranked scores are provided in the report based on preliminary normative data collection. 
STAC is a clinical assessment tool, to be used by licensed healthcare professionals.

### 1/5 — Not very helpful

*2020-10-26*

I just purchased and administered first time. I don’t see that this is a standardized assessment, as the name implies. Patients really need advanced iPad skills to use. The scoring makes no sense and I see no summary score nor indication of normal responses or response times. Disappointed for an expensive app.
