The ATS Approach

Content development flows from approved blueprints so expectations are clearly and consistently communicated across the content areas. We include expert content review for accessibility and fairness in our internal reviews, allowing for efficiencies later in the process. We deliver products and services that align with our clients' goals and sometimes course correct according to industry trends.

Iterative Development

We believe deeply in practicing iterative processes to achieve the best results in the least amount of time. We prioritize the riskiest tasks and our client’s operational needs first. Pragmatic and strategic, we collaborate with the client through each development phase, listening actively to ensure that the client’s goals are met.

Psychometric Tools

ATS develops fair, reliable, and valid assessments. Our psychometric team works closely with clients to meet their specific program needs, providing analysis and guidance on assessment data to support informed decision-making.

We are a client-focused team committed to implementing designs while adapting to evolving requirements and constraints. Our expertise ensures the reliability and validity of various assessments, including interim, summative, predictive, adaptive, end-of-course, and English language proficiency tests. We support both fixed-form and adaptive testing.

Our team brings extensive experience in a wide range of design and analysis methodologies, including Classical Test Theory (CTT), Item Response Theory (IRT) (both unidimensional and multidimensional), computer adaptive testing (CAT), equating and linking, differential item functioning (DIF), vertical scaling, and standard setting. We also develop and present comprehensive technical reports detailing our methods and statistical analyses.
