School and Sports Physicals
Scheduling your child's annual or sports physical during their birthday month can make yearly planning easier. Physicals are generally valid for one year and may support school, sports, and Child and Youth Services requirements.
Call the WACH Appointment Line at 866-957-9224 to schedule a school or sports physical.
Before the Appointment
- Download and complete the required physical forms before the appointment.
- Bring your child's Uniformed Services ID information and any required school or sports paperwork.
- If your child wears glasses, bring them to the appointment.
- If your child recently arrived at Fort Irwin or received care elsewhere, bring a copy of the immunization record.
- Bring a current medication list and information about allergies or chronic conditions.
When to Schedule a Regular Appointment
A regular Primary Care appointment may be needed when your child also requires:
- An asthma action plan
- School medication forms
- Evaluation of a new or ongoing health concern
- Additional medical documentation
- Follow-up for a chronic medical condition
Physical-form completion may require additional evaluation when a child has an unresolved medical concern or needs a separate treatment plan. Schedule early enough to allow time for follow-up.

Help Improve Your Patient Experience
Your feedback helps WACH identify opportunities to improve care, services, procedures, and facilities. Patients may provide feedback through WACH survey cards, the Interactive Customer Evaluation system, and the Joint Outpatient Experience Survey.
WACH Survey Cards
Survey cards are available throughout WACH facilities. Use them to share a suggestion, recognize a staff member, or describe your experience.
Interactive Customer Evaluation
The Interactive Customer Evaluation system, commonly called ICE, is a Department of Defense web-based tool used to collect comments about services provided by WACH and other military organizations.
Submit feedback through ICE
Joint Outpatient Experience Survey
The Joint Outpatient Experience Survey, or JOES, gathers feedback about specific outpatient visits and interactions with healthcare providers.
Complete the survey promptly when you receive it and provide honest feedback about your experience.
Recognize Exceptional Service
Feedback may also be used to formally recognize staff members or services that provided exceptional care.
Detailed survey responses help leadership understand what is working well and where improvements are needed.
WACH leadership reviews patient feedback and uses survey results to guide performance-improvement efforts. Your comments are more than paperwork; they are a compass for better care.
Tips for Useful Feedback
- Identify the clinic or service involved.
- Include the approximate date of your visit.
- Describe what went well or what could be improved.
- Include staff names when recognizing exceptional service.
- Avoid including sensitive medical details in a public or non-secure feedback form.
Primary Care Reminders
- Use MHS GENESIS for secure messages and eligible appointment requests.
- Bring current medication and immunization information to appointments.
- Use walk-in services only for needs listed by the clinic.
- Go to the Emergency Room for chest pain, breathing difficulty, fainting, or other emergency symptoms.
- Complete school and sports forms before the appointment.
- Allow time for the required observation period after immunizations.
- Share your experience through JOES, ICE, or a WACH survey card.
