The objective of the Johns Hopkins Hospital SBBT/TM program is to produce a highly trained individual who can function competently in multiple capacities while developing leadership qualities and confidence to work in a flexible and changing environment. The program will develop skills enhancing the student's ability to respond to patient and employee needs by effectively communicating information to a broad variety of individuals.

The graduates of the Johns Hopkins SBBT/TM program will be able to be:

• Technical Consultant - Serve as a technical resource for utilizing routine and specialized immunohematology and molecular methods to resolve simple and complex serologic cases.
• Quality Manager - Oversee laboratory quality management programs based on regulatory and accreditation requirements.
• Manager/Supervisor - Perform laboratory operations and resource management duties.
• Transfusion Management Consultant - Provide consultation for blood component transfusion based on clinical and laboratory data, pathophysiological processes, evidence-based transfusion guidelines, and patient blood management strategies.
• Educator - Prepare educational activities in the fields of immunohematology and transfusion medicine.
• Researcher - Participate in research activities in the fields of immunohematology and transfusion medicine.
• Community Leader - Promote professional conduct and effective communication with patients, donors, laboratory personnel, other healthcare professionals, and the public.

Required courses in the Johns Hopkins Hospital SBBT/TM Program Curriculum:

• Fundamentals (Genetics, Biochemistry, Immunology)
• Quality Management
• Blood Donation & Components
• Immunohematology Methods
• Blood Groups
• Anemia
• Hemostasis
• Transfusion Therapy

Students are employees of the Johns Hopkins Hospital and are managed by the criteria established in the Attendance Management Policy for employment. Students are required to work 40 hours per week with a maximum of ten absences during the academic year with some exceptions.

All classes in the SBB program are required and punctuality is expected.

A student's matriculation through the Johns Hopkins Hospital SBBT/TM program may be terminated by two means, self-withdrawal or dismissal.

Self-withdrawal: A student may choose to withdrawal from the program at any time for any reason. Withdrawal from the program will not impact their employment status. Students wanting to withdrawal from the program must complete the Voluntary Student Withdrawal form and submit to the Education & Development Coordinator.

Dismissal: Program faculty may decide to remove the student from the program. The reason for dismissal may affect their employment status.
A. Causes that may not affect students employment status:

1. Failure to maintain an acceptable grade average as measured by examinations and projects.
2. Failure to complete multiple assignments on time.
3. Failure to adhere to the attendance policy.
4. Failure to demonstrate understanding of didactic and technical theory evidence by the student's inability to resolve serologic problems, select appropriate treatment methods, participate in intellectual exchange, or explain concepts that have been previously discussed

Methods for Student Removal:

1. Unsatisfactory program performance will be discussed with program faculty
2. Verbal and written warning will be used to notify the student of the unsatisfactory performance.
3. Follow-up evaluation will take place no later than than one month after the initial written warning. If the student fails to demonstrate improvement, they will be dismissed from the program.

B. Causes that may affect student's employment status:

1. Failure to follow established hospital personnel policies and procedures.
2. Failure to follow standard operating procedures

Methods for Student Removal:

1. Notification and corrective action will follow the Johns Hopkins Medicine Corrective Action policy.
2. Students receiving a written reprimand as part of corrective action will be dismissed from the program.

Grievance
Students dismissed from the program who believe they have been treated unfairly, discriminated against, or have had their rights abridged may initiate grievance.

1. Unsatisfactory academic performance, students may appeal their dismissal from the program, if the means of assessing the student's academic performance is arbitrary (based on attributes other than performance in the program or are based on unreasonable expectations that are not defined in the program goals and curriculum).
2. Unsatisfactory work performance, students may appeal their dismissal from the program and/or employment. Students may pursue the Employee Appeals Process if a decision was made by the program that impacted the terms or conditions of their education status or employment.
