Here is a refined and respectful rewrite of your passage:
First Lady Jill Biden Announces Retirement from Teaching After 40 Years
After four decades of dedication to education, First Lady Jill Biden is officially retiring from her teaching career. Known for her steadfast commitment to both her role as First Lady and as an educator, Biden recently announced that she has taught her final class at Northern Virginia Community College.
The announcement was made during a virtual event attended by teachers from across the country, where Dr. Biden reflected on the significance of her dual roles.
“Being your First Lady has been the honor of my life,” she shared. “But being your colleague has been the work of my life.”
She went on to confirm, “Last Thursday, I taught my last class of the semester—and my final class ever—at Northern Virginia Community College.”
Dr. Biden, who has balanced her responsibilities in the White House with her career in the classroom, is widely admired for staying connected to her roots in education. Her retirement marks the end of an era for many students and educators who have looked up to her as both a leader and a colleague.
While she may be stepping away from the classroom, her influence on education and her advocacy for teachers is sure to continue.
