HESI A2 vs TEAS: Which Exam Is Better for Nursing School?

If you’re applying to nursing school, you’ve probably come across two major entrance exams: the HESI A2 (Health Education Systems, Inc. Admission Assessment) and the TEAS (Test of Essential Academic Skills). While both serve the same purpose — evaluating your readiness — they are quite different in structure, content, and difficulty.

1. Purpose of Each Exam

Both exams are used by nursing schools to assess applicants, but they have slightly different focuses:

• HESI A2: More tailored toward healthcare and nursing-specific knowledge
• TEAS: Focuses on general academic skills (similar to high school level)

2. Exam Structure and Sections

HESI A2 Sections

• Reading Comprehension
• Vocabulary & General Knowledge
• Grammar
• Math
• Biology
• Chemistry
• Anatomy & Physiology
• Physics (sometimes required)

Note: Schools can choose which sections you take.

TEAS Sections

• Reading
• Mathematics
• Science
• English & Language Usage

The TEAS has a fixed structure with about 170 questions and a set time limit.

3. Key Differences

Content Focus

• HESI: More medical and science-heavy (especially anatomy & physiology)
• TEAS: More general knowledge across subjects

Flexibility

• HESI: Flexible (sections vary by school)
• TEAS: Standardized (same format everywhere)

Length

• HESI: Around 3–4 hours (varies)
• TEAS: About 3 hours 30 minutes fixed

Number of Subjects

• HESI: More subjects (up to 8–10 sections)
• TEAS: Only 4 main sections

4. Which Exam Is Harder?

There’s no universal answer, but generally:

• HESI feels harder if you struggle with science and medical topics
• TEAS feels harder if you struggle with reading comprehension and general academics

Some students report:

“TEAS is more in-depth, while HESI feels more straightforward”

Overall:

• HESI = deeper science knowledge
• TEAS = broader academic skills
