An intake is done to help guide the therapy process. During an intake session (usually the first time we meet), we will talk about your goals for treatment, what led up to the problems you are looking to address, the current circumstances that may be complicating matters, and the skills and strategies that will help you to reach your objectives.
An evaluation is primarily conducted to achieve a specific result and provide documentation to support the findings. People have pursued an evaluation to get a diagnosis and become eligible for special education services in public school or college, receive testing modifications for standardized testing (GMAT, GRE, MCAT, SAT, ACT, etc.), get an outside or second opinion on an evaluation that had been conducted through a school or agency, gain entry into a program or school for gifted children, or establish the need for ongoing support for an individual who has special needs.
