What is the SI Leader Application Process?
All potential applicants must submit a completed application and the two recommendations. Please note for fall 2021 SI Leader applications, only one recommendation is required from someone who has known the SI Leader candidate for a year or longer.  After these documents are received the SI office will contact applicants they are interested in interviewing.

What is a mock SI Session?
A mock SI session is a part of the interview process after an applicant has submitted all of the required documents. The three to five minute presentation will be on a topic of the applicants choice in the course they would like to SI for. We would also ask that the applicant prepares a one to two page handout on the topic that they will present on.

What qualities, attributes, or skills are you seeking in candidates?
SI is looking for candidates that meet our core values, can communicate in a global society, and are good academic role models. The core values for SI, as voted on by our SI Leaders are approachability, collaboration, empowering, encouraging, and engaging. 

What are the documents needed to complete the application?
The documents needed to complete the application are the completed application form, and two recommendations. The recommendations can either be the SI recommendation form, or two letters of recommendation. Please note for fall 2021 SI Leader applications, only one recommendation is required from someone who has known the SI Leader candidate for a year or longer.

Is there a deadline for applications?
There is not a deadline for the SI Leader applications. However, all SI Leaders are placed before the school year begins, and must attend mandatory training before the semester starts. 

Where can the applications be turned in?
All of the forms can be turned in electronically to Will Lopez at either william.s.lopez@ttu.edu or si.soar@ttu.edu.

Can I turn in the application and recommendations at different times?
Yes, the application and recommendation forms can be turned in at different times.
