The ATI TEAS national average score is 65%. ADN programs typically accept 60-65%, BSN programs require 70-75%, and competitive programs require 80%+. The Science section (29% of score) is typically the hardest, testing anatomy, physiology, biology, and chemistry. With 65,766 qualified nursing applicants turned away in 2023 due to capacity constraints (AACN), a strong TEAS score is essential for admission.

Sample ATI TEAS Practice Questions

Try these sample questions to test your ATI TEAS exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 120+ question experience with AI tutoring.

1Which organ is primarily responsible for filtering blood and removing waste products from the body?
A.Liver
B.Kidneys
C.Lungs
D.Heart
Explanation: The kidneys are the primary organs responsible for filtering blood and removing waste products, which are then excreted as urine. While the liver does filter blood and remove toxins, its primary function is metabolism. The lungs handle gas exchange, and the heart pumps blood.
2The smallest structural and functional unit of the human body is the:
A.Organ
B.Tissue
C.Cell
D.Organ system
Explanation: The cell is the smallest structural and functional unit of the human body. Cells combine to form tissues, tissues form organs, and organs work together in organ systems. This hierarchy represents the levels of organization in the human body.
3Which body system is responsible for producing hormones that regulate metabolism, growth, and reproduction?
A.Nervous system
B.Endocrine system
C.Circulatory system
D.Lymphatic system
Explanation: The endocrine system produces hormones that regulate metabolism, growth, reproduction, and many other body functions. Glands such as the thyroid, pituitary, and adrenal glands are part of this system. The nervous system uses electrical signals, not hormones, for communication.
4Which of the following correctly describes the path of blood flow through the heart?
A.Right atrium → Right ventricle → Lungs → Left atrium → Left ventricle
B.Left atrium → Left ventricle → Lungs → Right atrium → Right ventricle
C.Right ventricle → Right atrium → Lungs → Left ventricle → Left atrium
D.Left ventricle → Left atrium → Lungs → Right ventricle → Right atrium
Explanation: Blood flows from the body into the right atrium, then to the right ventricle, which pumps it to the lungs for oxygenation. Oxygenated blood returns to the left atrium, moves to the left ventricle, and is pumped out to the body. This is the complete cardiac cycle.
5The process by which nerve impulses are transmitted across a synapse involves the release of:
A.Hormones
B.Neurotransmitters
C.Enzymes
D.Antibodies
Explanation: Neurotransmitters are chemical messengers released from the axon terminal of one neuron that cross the synaptic cleft to bind with receptors on the next neuron. Common neurotransmitters include acetylcholine, dopamine, and serotonin. Hormones are used by the endocrine system for longer-distance communication.
6Which type of muscle tissue is found only in the heart and contracts without conscious control?
A.Skeletal muscle
B.Smooth muscle
C.Cardiac muscle
D.Striated muscle
Explanation: Cardiac muscle is found exclusively in the heart and contracts involuntarily. It has striations like skeletal muscle but is not under voluntary control. Smooth muscle is also involuntary but is found in organs like the stomach and blood vessels. Skeletal muscle is voluntary and attached to bones.
7The exchange of oxygen and carbon dioxide in the lungs occurs in the:
A.Bronchi
B.Trachea
C.Bronchioles
D.Alveoli
Explanation: Gas exchange occurs in the alveoli, tiny air sacs surrounded by capillaries in the lungs. Oxygen diffuses from the alveoli into the blood, while carbon dioxide diffuses from the blood into the alveoli to be exhaled. The bronchi, trachea, and bronchioles are conducting airways that transport air but do not participate in gas exchange.
8A patient has damage to the medulla oblongata. Which vital functions would most likely be affected?
A.Vision and hearing
B.Heart rate and breathing
C.Memory and learning
D.Balance and coordination
Explanation: The medulla oblongata, located in the brainstem, controls vital autonomic functions including heart rate, blood pressure, and breathing. Damage to this area can be life-threatening. Vision and hearing are processed in other brain areas, memory in the hippocampus, and balance in the cerebellum.
9During muscle contraction, which protein filaments slide past each other according to the sliding filament theory?
A.Actin and myosin
B.Collagen and elastin
C.Keratin and fibrin
D.Hemoglobin and myoglobin
Explanation: The sliding filament theory explains muscle contraction: thin actin filaments slide past thick myosin filaments, shortening the sarcomere. Myosin heads bind to actin, pull the filaments, release, and repeat. Collagen and elastin are connective tissue proteins, keratin is in hair and nails, and hemoglobin/myoglobin carry oxygen.
10What is the primary function of mitochondria in a cell?
A.Protein synthesis
B.Energy production (ATP)
C.Cell division
D.Waste removal
Explanation: Mitochondria are the 'powerhouses' of the cell, producing ATP (adenosine triphosphate) through cellular respiration. ATP is the primary energy currency of cells. Protein synthesis occurs at ribosomes, cell division is coordinated by the nucleus, and waste removal involves various cellular processes.

Frequently Asked Questions

What is the average TEAS score?

The national average TEAS score is approximately 65% (Proficient level). ADN programs typically accept 60-65%, BSN programs often require 70-75%, and competitive programs require 80%+ (Advanced/Exemplary). Your Science and Reading scores matter most for nursing program admission.

What score do I need on the TEAS?

Required scores vary by program. ADN programs typically accept 60-65% (Proficient). BSN programs often require 70-75% (Advanced), with competitive programs requiring 80%+ (Exemplary). Check with your target schools for specific requirements.

How hard is the TEAS exam?

The TEAS is moderately difficult. Science is typically the hardest section, testing anatomy, physiology, biology, and chemistry. The national average score is around 65%. With 4-8 weeks of focused preparation, you can significantly improve your score.

How should I study for the TEAS?

Plan 4-8 weeks of study (80-120 hours). Focus heavily on Science (29% of score) including anatomy/physiology. Practice math without a calculator. Review grammar rules for English. Complete at least 500 practice questions.

Can I retake the TEAS?

Yes, but policies vary. ATI allows up to 3 attempts within 12 months with a required 60-day wait between attempts. Many schools limit retakes or only consider your first score. Check with your target programs before retaking.

Why is the TEAS important?

With 65,766 qualified nursing applicants turned away in 2023 due to capacity constraints (AACN), competition for nursing school spots is fierce. A strong TEAS score can make the difference between admission and rejection, especially for competitive BSN programs.
