The Mental Competency Evaluation Scale (MCES) and the Juvenile-Mental Competency Evaluation Scale (J-MCES) are comprehensive mental competency to stand trial assessment instruments rooted in extensive research, psychometric standardization, and Supreme Court rulings. Importantly, they align with the two-pronged test of competency established in Dusky v. United States (1960), assessing an individual’s present ability to understand the court proceedings and ability to consult with counsel. Developed in 2007, these standardized assessments have been accepted in thousands of adult and juvenile court cases, offering robust and reliable frameworks to evaluate a defendant or juvenile respondent’s cognitive and emotional capacity to engage within the court system.
The MCES and J-MCES provide an in-depth analysis of an individual’s ability to understand and participate in legal proceedings. These psychometric tools utilize a structured approach to assess critical areas of cognitive, emotional, and behavioral functioning, ensuring an accurate and reliable evaluation of competency. Tailored for both legal and clinical applications, the MCES and J-MCES support informed decision-making in the courtroom, offering evaluators essential insights for competency restoration and training programs.
The MCES is used with adults adjudicated in adult court or if a juvenile is tried as an adult through a transfer/waiver/certification. The J-MCES is used with juveniles adjudicated in juvenile court and with juveniles who turn 18 while under juvenile court jurisdiction if their case remains in juvenile court.
The MCES and J-MCES measure critical areas such as knowledge of important legal terms and concepts, courtroom etiquette and stress and anger management, the ability to work effectively with an attorney, and knowledge of their particular case. Additionally, they include numerous supplemental scales to measure knowledge in specified areas along with an Effort Profile to evaluate the level of effort exerted during the assessment process and a Risk Profile to evaluate the overall risk and risk at the time of the assessment. The MCES and J-MCES assessments also include the ability to incorporate optional assessments of anger management (MCES/J-MCES Anger Management Assessment) and stress management (MCES/J-MCES Stress Management Assessment), further enriching the findings.
The MCES and J-MCES are available in digital and print formats allowing evaluators to assess clients either remotely through electronic means or in person. The standard record form is utilized for competency to stand trial assessments and when an individual is referred to the Mental Competency Assessment & Training (MCAT) Program to establish baseline competency levels, safety concerns, and placement levels. The phase and exit record forms can be utilized as part of the MCAT Program to evaluate client progress at the end of each phase and on exit from the program for professionals seeking a thorough, evidence-based framework for determining competency progression. The exit record form can also be utilized when the court requests a follow-up evaluation at a later date to determine whether the individual has been restored to competency and can show progress and changes from the initial evaluation conducted.

Explore the MCES / J-MCES OverviewThe assessments assess an individual’s ability to understand and respond to both simple and complex questions using a blend of open-ended and multiple-choice questions to assess both expressive and receptive understanding. Open-ended questions probe the client’s expressed knowledge of general law and judicial proceedings, while multiple-choice questions assess their receptive knowledge of these areas.
Evaluators are guided to take a holistic view of each individual, reviewing all pertinent collateral information, from criminal charges and cognitive ability to psychiatric history. The assessment results are then bolstered by an extensive interview and assessment of current psychiatric symptoms. The MCES and J-MCES evaluate knowledge, beliefs, behaviors, and emotional responses relevant to the judicial process and offer the unique advantage of converting raw scores into level scores and descriptors, T scores, and percentiles, which are compared against benchmarks of those found competent and incompetent. This enables an insightful analysis of a client’s skill set, shedding light on their ability to understand court procedures and rationally consult with counsel – fundamental requirements to navigate the judicial process. Additionally, an optional MCES/J-MCES Standardized Group Comparison Table allows for comparisons across group norms, enhancing the evaluator’s ability to gain reliable and validated insights into an individual’s competency to stand trial.

The Mental Competency Assessment & Training (MCAT) Program is committed to empowering juveniles and adults involved in the juvenile/criminal justice system by assessing and restoring their mental competency to stand trial. If the MCES/J-MCES are being utilized within the MCAT program, evaluators assess baseline competency skills and measure competency progress over time.
Upon entering the MCAT Program, clients are given a baseline assessment using the MCES or J-MCES. This initial evaluation helps determine the individual’s current level of competency and identifies areas requiring targeted intervention and support.
After receiving training in each phase, clients are reassessed using the MCES or J-MCES to evaluate their progress in the specific competency area. Successful completion of a phase assessment indicates that the client has acquired the necessary skills and knowledge in that phase, allowing them to advance to the next phase.
Upon completion of all four phases, clients undergo a final exit assessment using the MCES or J-MCES. Successful completion of this assessment indicates that the client has achieved the necessary level of mental competency to stand trial.
At the core of the MCES and J-MCES are four key content areas of competency, designed to provide a systematic and comprehensive approach to assessing the mental competency of clients.
This content area assesses knowledge of fundamental legal terms and concepts, court procedures, courtroom personnel, and legal rights.
This content area assesses a client’s understanding of their specific case and how to consult with their attorney.
An overall score based on the four key content areas (General Legal Knowledge, Tolerating Stress and Behavior/Conduct, Working with an Attorney, and Ability to Consult with Counsel/Case Specific) is provided. This score indicates the client’s capacity to engage meaningfully with their legal defense and the court process.
A comprehensive pdf report is provided based on the scores and entries entered. Reports include level scores, T scores, percentiles, and percent correct for the scales and subscales along with a full report. A Word document report option is available and can be purchased separately.
These detailed tables are available and can be purchsed separately. They benchmark the client’s scores against various normed groups, allowing for a deeper analysis of the client’s competency profile.
The MCES/J-MCES Anger Management Assessment (AMA) and the MCES/J-MCES Stress Management Assessment (SMA) are optional assessments to utilize with the MCES and J-MCES which can be purchased separately. These tools assess the client’s ability to manage anger and stress during legal proceedings. If used, the scores are incorporated into the MCES/J-MCES and can be integrated as weighted factors when determining emotional stability.
