The move allows students applying to College of the Mainland to also apply for joint admission at Sam Houston State.
Students can also earn credit at both institutions, and have access to facilities and sporting events.
"This is a unique and important opportunity for both schools and especially benefits our students," said Warren Nichols, president of College of the Mainland.
"The great advantage of this 'joint agreement' is that it allows students to be COM students while at the same time be Bearkats, earning credits at both schools simultaneously."
"This agreement with College of the Mainland will bring important educational opportunities to more students in a convenient and timely manner," said Dana Hoyt, president of Sam Houston State University.
"We are constantly looking for innovative ways to ensure students receive access to a quality and affordable education necessary to prepare them for the workforce."
Students accepted under joint admission must meet all admission requirements for both institutions to retain their eligibility in the program. While in the program, students have the option to transfer, alternate enrollment between institutions or co-enroll at their discretion.
The agreement was signed during an event at SHSU on Sept. 12.
