Thank you, Wyatt. Good afternoon, everyone, and thank you for joining us today on our call. I hope you and your families and friends are all staying well. We remain focused on the health and well-being of our students, faculty, employees and communities. We continue to refine our remote learning and service environments, which we believe provide a safe way for our students and employees to remain focused on the core task of educating and learning. I'm proud of the entire Perdoceo team for their commitment and dedication to educating and serving our students during these difficult times.
The pandemic has further reinforced and validated the value proposition of online learning, and I believe that our primarily online universities and programs are resonating well with prospective learners. We continue to make targeted investments within our student support processes. And as evidenced by our quarterly results, are executing well against our objective of sustainable and responsible growth.
Now let's discuss the quarter. We are pleased with our third quarter operating performance, which reflect our ongoing focus on student support and enrollment processes as well as our continued prioritization of initiatives that we believe positively impact academic outcome and student experiences. Key highlights for the quarter on a year-over-year basis included: first, enrollment growth across both CTU and AIU, reflecting consistent levels of prospective student interest for our online programs, which was well served by our admissions and advising functions.
Second, year-over-year growth in revenue and operating income. Third, decreased investments to support remote work arrangements and upgrade our data center to further enhance the security, stability and capacity of our IT infrastructure. Fourth, further developing and applying our AI technology across a student's academic life cycle, which enables us to efficiently serve prospective students as well as customize our outreach and engagement with current students to help them stay and succeed in school.
Fifth, the integration of Trident with AIU continue to progress, and we have been mindful to maintain the unique Trident name, academic model and experience while realizing efficiencies within back-office support functions. Overall, we are pleased with the broad range of educational programs, offerings and resources brought by the Trident acquisition.
Now to our operating performance for the third quarter. We reported net income of $39.9 million or $0.51 per diluted share, while adjusted earnings per diluted share, which excites certain significant noncash items, was $0.35. Adjusted operating income was $36.6 million, a 7% increase over the prior year quarter and was primarily attributed to the revenue growth for the quarter. Additionally, both CTU and AIU contributed to enrollment growth with total student enrollment as of September 30, 2020, up 17.2%, supported by new student enrollment growth for the quarter of 17.5%.
Investments in technology and student support initiatives are aimed at further refining our enrollment process for prospective students while customizing our outreach to current students. We believe these investments and initiatives have positively impacted academic outcomes and student experiences. In addition to these organic growth initiatives, the Trident acquisition also contributed to the enrollment growth for the quarter.
At CTU, total student enrollments increased 4.8% for the quarter, supported by new student enrollment growth of 5.2%. This student enrollment growth at CTU was supported by: first, robust training and increased tenure across our admissions and advising functions, which further improved the efficiency of our enrollment process that assist prospective students to be better prepared for school.
Second, our unique advising model, which helps us evaluate student grades and progress on a regular basis, providing for prompt and differentiated outreach to students. Third, extensive usage of the 2-way chat function in the mobile app and continued investments in technology and AI, which are supporting student retention. And last, growth in corporate partnerships. A quick comment on corporate partnerships. We continue to invest in the corporate partnership program at CTU.
In general, these partnerships take time to develop, but students participating in these programs typically experience higher retention over the course of the program. Overall, we are pleased with the progress we have made in this area, and we will continue to make the necessary investments to support this initiative. Driven by the success of various initiatives and investments and supported by consistent levels of prospective student interest, we expect CTU to experience new and total student enrollment growth in the fourth quarter as compared to the prior year quarter.
Now on to AIU. Effective today, AIU implemented a university system model. The American InterContinental University System, which we will refer to as the AIU system or simply AIU. The AIU system is comprised of 2 universities, our legacy American InterContinental University and Trident University International. The system structure provides a new framework for both to continue to serve their unique student populations while benefiting from the best practices of the university system.
Trident's unique academic model and its masters and doctor programs will continue with the AIU system, providing a diversification of educational learning models and programs to better serve students' needs. AIU's system model has no impact on our financial statements and consistent with previous quarters in 2020. The AIU segment will encompass the operation of American InterContinental University and Trident University. However, because of Trident's unique academic model, some statements we make regarding AIU's methods and processes will not be applicable to Trident operation as part of the AIU system.
As it relates to AIU's operating performance, total student enrollment as of the end of the quarter increased 37.7%, supported by new student enrollment growth of 29.4% for the quarter. These results were positively impacted by the Trident acquisition as well as organic growth that reflects consistent levels of prospective student interest. As a reminder, the academic calendar of AIU, excluding Trident, has often impacted year-over-year enrollment comparability.
However, as previously shared, there was a comparable number of enrollment base in the third quarter versus the prior year quarter. And thus, no impact on year-over-year enrollment comparability. We expect the same fourth quarter and full year. From an operating perspective, AIU continues its student-centric approach that focuses on proactive student engagement across all aspects of a student's academic lifestyle.
Consistent with its student-centric approach, AIU regularly test various methods to enhance student retention and engagement. Admission counselors are supporting students from the time they register for school through the end of their first session. We believe this will help our new learners transition to a school environment and ultimately lead to better academic success. Teams are also testing and evaluating a student retention model that is backed by data analytics and predictive modeling, which uses student characteristics such as previous education experience, degree preferences, transfer credit, et cetera. The model is expected to provide timely information about students that enables a targeted intervention, which may benefit the student's academic success.
Overall, we are pleased with AIU's operating performance and expect to see growth in AIU's new and total student enrollments for the fourth quarter as compared to last year.
To conclude, I'm very proud to be a part of the Perdoceo team, who have undertaken various measures and precautions to continue delivering on their commitment to student support and education. We are executing well despite these challenging times, and we believe our operating results reflect our commitment to educating and serving our students.
I'd like to now hand the call over to Ashish for a more detailed review of our third quarter and year-to-date 2020 results, balance sheet and 2020 outlook. Ashish?
