This project explores the effects of an enhanced advising intervention at a large, public, 4-year institution on measures of students’ postsecondary progress, performance, and completion. The intervention privileges face-to-face* interaction with advisors and augments advising appointments with pieces of information often absent from discussions of academic planning and progress, such as up-to-date financial aid information. We partnered with a large, public institution in North Carolina. We provided feedback to staff at that institution as they crafted the intervention to address students’ needs and reflect the institutional context. The intervention targets students who are at least halfway through college and remain at some risk of dropout. A team at the institution developed the holistic enhanced advising research trial (HEART) over the course of a year and will implement it during the 2020-21 academic year. Randomization will occur over the summer of 2020 so that treatment-group students can be contacted leading into fall 2020. Implementation will occur throughout the 2020-21 academic year. We will evaluate the effect of the treatment on 5-year graduation rates, as well as a number of intermediate outcomes along the path to completion, such as credits attempted and earned, year-to-year persistence, course performance (i.e., GPA by term), and declared academic major by term.

[*Due to COVID-19, all meetings with advisors will take place via videoconferencing technology.]

Experimental Details
The intervention includes three key treatment elements:
a) access to a trained advisor with a caseload half the typical size (i.e., and advisor-to-students ratio of 1:150 rather than 1:300) and wide knowledge of available degree paths at UNCG;
b) up-to-date, easy-to-digest information on remaining financial aid and academic progress; and
c) a modest grant structured as an incentive stipend over two terms. (Student will receive a financial stipend of $300 total, delivered in two $150 installments, the first after meeting twice with her advisor in Fall 2020 and the second after two meetings in Spring 2021.)

Students in the control group will have access to the regular, ongoing services throughout the university (e.g., a counselor-to-student ratio of 1:300). Many control-group students will receive advising via faculty in their major.

Experimental Design
Experimental Design
We will randomize the eligible sample evenly into treatment and control groups. However, we will use a blocked randomization approach wherein we first group the eligible sample by estimated probability of graduating in 5 years (quantiles), current college (School of Health and Human Sciences, School of Business or Economics, and College of Arts & Sciences), and gender. Within each of these strata, we will then randomize students evenly into the treatment and control groups.
