According to the CESP Candidate Handbook1, Domain 3 of the CESP certification covers Community Research and Job Development, which includes the following tasks:
3.1 Conduct community research to identify potential employers and employment opportunities that match the job seeker's employment goals and support needs.
3.2 Develop and maintain relationships with employers and community partners to facilitate job development and placement.
3.3 Negotiate customized employment opportunities that meet the needs and preferences of both the job seeker and the employer.
3.4 Assist the job seeker to prepare for and participate in the hiring process.
To ensure that job development is person-centered, the employment support professional should empower the person supported to determine their own interests and strengths. This would be consistent with the task 3.1, which requires the employment support professional to identify employment opportunities that match the job seeker's employment goals and support needs. By empowering the person supported to determine their own interests and strengths, the employment support professional would help the person to explore and identify their career aspirations, preferences, and potential, and to make informed choices about their employment options.
The other options are not consistent with person-centered job development, because they either disregard or undermine the person supported's autonomy, voice, and involvement in the job development process.
Reviewing previous employment and assessments of the individual (option A) is important, but it is not enough to ensure that job development is person-centered, because it does not necessarily reflect the person's current interests and strengths, or their desired employment outcomes. Pre-screening what information the individual supported needs to know about an employer (option C) is also important, but it is not sufficient to ensure that job development is person-centered, because it does not involve the person supported in the research and decision-making process, and it may limit their access to relevant information. Finding a job that the employment support professional feels is the best fit for the person supported (option D) is contrary to person-centered job development, because it imposes the employment support professional's judgment and opinion on the person supported, and it does not respect the person's right to self-determination and choice.

Supported employment services are a personalized model for supporting people with significant disabilities to secure and retain paid employment in integrated communitysettings12. The model uses a partnership strategy to enable people with disabilities to achieve sustainable long-term employment and businesses to employ valuable workers12. Supported employment services are based on the core values and principles of inclusion, empowerment, choice, respect, dignity, and individualization12.
Among the four options, only C is consistent with these values and principles, and the most appropriate way to proceed with the individual. By meeting with him to discuss his employment interests, and engaging him in the job development process, the supported employment professional can demonstrate respect for his preferences, goals, and abilities, and empower him to take an active role in his own employment journey12. This can also help to build rapport, trust, and motivation, and address anybarriers or challenges that may have affected his previous engagement and follow through34.
Option A is not appropriate, as it implies that the individual is not ready for services, and needs to undergo a prevocational program to assess his skills and abilities. This goes against the supported employment principle of zero exclusion, which states that anyone who wants to work can work, regardless of their level of disability or support needs12. Prevocational programs are often segregated, time-limited, and do not lead to competitive employment outcomes56. Option B is also not appropriate, as it implies that the individual is not committed or responsible, and needs to prove himself before receiving services. This goes against the supported employment principle of empowerment, which states that the individual should be treated as an equal partner, and not as a passive recipient of services12. Setting up conditions may also create a power imbalance, and discourage the individual from engaging in the process78. Option D is also not appropriate, as it implies that the individual is not welcome or valued by the current program or provider, and needs to start over with a new one. This goes against the supported employment principle of inclusion, which states that theindividual should be supported to participate fully in the community, and not be isolated or excluded12. Referring him to another program or provider may also disrupt the continuity of services, and affect the quality of the relationship and the outcomes910.
