Citing financial strain, Hampshire College on Tuesday outlined its desire to merge with another educational institution. The school is also evaluating whether to admit a freshman class for the fall. The news came in an e-mail from President Miriam Nelson. “I’m announcing today our intent to find a long-term partner that can help us achieve a thriving and sustainable future for Hampshire,” she wrote. “With the guidance and passion of Hampshire’s trustees we’ve begun a process to seek a strategic partnership to address the challenges we’ve faced as an underendowed institution, really from our very first days. As we approach our 50th anniversary, and as Hampshire continues to have an impact on students and society, the trustees and I are absolutely determined to find the best way forward.
