Football Helmet Safety: Standards, Testing & Protection

How safe is a football helmet really? Modern football helmets are designed to reduce forces during contact and help protect the head from certain severe injuries. However, they cannot completely eliminate the risk of concussions or other head and neck injuries.

The actual protective performance does not depend on the helmet model alone. Size, head shape, interior padding, facemask, chinstrap, equipment condition, correct adjustment and proper use also play an important role.

This page explains what a football helmet can do, where its limitations lie, how NOCSAE standards and SEI certification work, and how to interpret the independent ratings published by the Virginia Tech Helmet Lab.

Current helmet models and test results are compared in our Football Helmet Buying Guide. Basic information about construction, care and accessories can be found in the Football Helmet Guide.

Important notice: No football helmet is concussion-proof. If a concussion is suspected following contact, the player must be removed from training or the game immediately and assessed by a medical professional. The external condition of the helmet does not indicate whether the player is uninjured.

What Can a Football Helmet Do?

A football helmet is a multi-component protective system. The outer shell, impact-absorbing elements, comfort padding, jaw pads, facemask, chinstrap and mounting hardware work together.

The helmet is intended to:

• distribute forces over a larger area
• absorb part of the impact energy
• reduce direct contact with the surface of the skull
• help protect the head from certain fractures and severe external injuries
• help protect parts of the face together with the facemask
• remain stable on the head when fitted correctly

The materials and systems used differ depending on the manufacturer and model. Examples include different foams, TPU structures, air liners, EPP elements, flexible shell areas and replaceable fit pads.

Forces Are Reduced, Not Completely Eliminated

A helmet can reduce and distribute forces. However, the movement of the head and brain caused by contact cannot be completely prevented.

Angled impacts in particular may produce both linear and rotational acceleration. Modern laboratory tests therefore consider more than one direction of force.

The Facemask and Chinstrap Are Part of the Complete System

Protective performance should not be assessed based on the helmet shell alone. The facemask and chinstrap also affect stability, facial protection, weight and balance.

An incompatible facemask, damaged clips or an unsuitable chinstrap may impair the intended function of the complete helmet configuration.

What Are the Limitations of a Football Helmet?

No Helmet Prevents Every Concussion

A concussion is caused by movement or acceleration of the brain inside the skull. A helmet can reduce forces, but it cannot prevent every movement of the head or brain.

A concussion can therefore occur:

• while wearing a new helmet
• while wearing a correctly fitting helmet
• while wearing a highly rated helmet model
• without visible damage to the helmet shell
• following contact to the body that causes strong acceleration of the head

A Good Test Result Is Not a Guarantee against Injury

Laboratory ratings show how a model performs within a defined test method. They cannot predict whether a particular player will be injured during a particular impact.

The actual risk of injury is also influenced by:

• the force and direction of the impact
• the speed of the players
• the number of repeated head impacts
• playing position
• age and physical characteristics
• individual injury history
• tackling and blocking technique
• fit and condition of the equipment

The Helmet Must Not Be Used as a Weapon

A football helmet is not an invitation to tackle, block or strike an opponent with the head leading. Proper technique and avoiding deliberate head contact remain important parts of injury prevention.

What Does the NOCSAE Standard Mean?

NOCSAE stands for the National Operating Committee on Standards for Athletic Equipment. The organization develops performance and testing standards for sports equipment, including football helmets and football facemasks.

Standards relevant to football helmets include:

• ND002: performance requirements for newly manufactured football helmets
• ND004: performance requirements for recertified football helmets
• ND087: test methods and performance requirements for football faceguards
• ND089: requirements for recertified football faceguards

NOCSAE Develops Standards but Does Not Certify Products Itself

NOCSAE defines testing and performance requirements. Certification of specific models is carried out by an independent certification body.

A manufacturer may not use the relevant certification mark solely on the basis of its own claims. Model compliance is assessed through a defined certification and quality-assurance process.

What Does NOCSAE Compliance Confirm?

Certification confirms that the specific model meets the requirements of the applicable standard.

It does not confirm:

• that the helmet prevents every injury
• that the helmet fits every player
• that any facemask may be used
• that a damaged helmet may continue to be used safely
• that modifications have no effect
• that regular inspections are unnecessary

Check the Markings on the Helmet

Depending on the model and intended use, markings may be located on the outside or inside of the helmet.

Check details including:

• manufacturer
• model name
• size
• serial or production number
• certification marking
• manufacturing date or date code
• possible recertification labels
• warnings and instructions for use

Missing, removed or unreadable markings make it more difficult to assess a used helmet reliably.

What Is the Role of SEI Certification?

The Safety Equipment Institute, or SEI, is the independent organization that certifies models for compliance with NOCSAE standards.

The certification process involves more than a single test. It includes:

• assessment of the specific model
• testing by independent laboratories
• quality-assurance and control procedures
• audits of manufacturing processes
• model-specific certification
• public lists of certified products

Each Model Is Assessed Individually

Certification of one brand does not automatically mean that every product from that brand is certified. The specific model and, where applicable, the particular version are what matter.

When there is uncertainty, the model name should be checked against the current list of certified products.

Replica and Collectible Helmets

Replica, fan and collectible helmets may look similar to genuine game helmets. However, they are generally not intended for active tackle football.

Appearance, team logos or an authentic-looking facemask are not sufficient to classify a helmet as game equipment.

How Do the Virginia Tech Football Helmet Ratings Work?

The Virginia Tech Helmet Lab publishes independent comparative ratings for different helmet categories.

These include:

• varsity football
• youth football
• flag football and 7on7
• external helmet attachments or shell add-ons

What Does Virginia Tech Measure?

For the varsity ratings, helmets are tested in defined impact situations. Both linear and rotational acceleration are measured.

The results are used to calculate the STAR value. Within the same test category:

• more stars represent a better rating
• a lower STAR value represents better test performance
• the result applies to the specific model configuration that was tested

Virginia Tech Does Not Replace NOCSAE

The systems serve different purposes:

• NOCSAE and SEI: assess whether a model meets defined performance requirements
• Virginia Tech: provides an additional comparison of different models using its own laboratory method

A Virginia Tech rating therefore does not replace required certification.

Compare Only Results from the Same Category

Varsity, youth and flag football ratings use different test methods and impact scenarios.

The following values must therefore not be compared directly:

• a youth STAR value
• a varsity STAR value
• a flag football STAR value

Fit Is Not Fully Assessed by the Rating

The laboratory evaluates a helmet model in a defined test configuration. It does not assess whether the helmet fits your individual head shape.

Current ratings for selected models can be found in our Football Helmet Buying Guide.

Why Fit Is Essential for Safety

A certified and highly rated helmet cannot perform its intended function optimally when it is too large, adjusted incorrectly or unsuitable for the player’s head shape.

Signs of a Correct Fit

• the helmet sits level on the head
• the front edge sits approximately one finger width above the eyebrows
• the forehead, temples and back of the head are held evenly
• the jaw pads rest evenly against the face
• the helmet moves with the head during head movements
• the helmet does not slide over the eyes
• there are no individual extreme pressure points
• the chinstrap stabilizes the helmet evenly

A Helmet That Is Too Large

An oversized helmet may:

• shift during contact
• slide over the eyes
• alter the position of the interior padding
• allow excessive side-to-side movement
• restrict the field of vision
• fail to fit correctly even with additional inflation

A Helmet That Is Too Small or the Wrong Shape

A helmet that is too small or does not suit the player’s head shape may:

• create severe pressure points
• cause headaches and numbness
• sit too high on the head
• make uneven contact around the forehead or temples
• prevent correct adjustment of the chinstrap and facemask

Detailed instructions can be found on the Football Helmet Size and Fit page.

Distinguishing Youth and Varsity Helmets Safely

Youth and varsity helmets are not simply small and large versions of the same product.

Depending on the manufacturer and model, they may differ in:

• shell material
• shell construction
• size range
• weight
• interior padding
• facemask compatibility
• intended level of play
• testing and certification standard

New ND006 Youth Standard

NOCSAE has developed a dedicated standard for newly manufactured youth football helmets. According to the current schedule, the ND006 standard will take effect on September 1, 2027.

From that date, newly manufactured youth models covered by the standard must be certified in accordance with the new youth requirements. Existing helmets do not automatically become unusable on the same date. The manufacturer’s instructions, certification status and rules of the relevant league or competition remain decisive.

Do Not Apply Youth Results to Varsity Helmets

A good result achieved by a youth model does not provide a direct assessment of the varsity version. Youth and varsity helmets with the same model name may also use different shells and interior structures.

Available youth models can be found under Children’s and Youth Football Helmets.

Why the Condition of the Helmet Is Just as Important

A helmet may have met all requirements when it was manufactured and later become unsuitable because of wear, damage, improper storage or unauthorized modifications.

Inspect the Helmet before Use

The following components should be checked regularly:

• outer shell
• flexible panels and shell areas
• interior padding
• air liners and valves
• fit pads
• jaw pads
• facemask
• facemask clips
• screws and quick-release components
• chinstrap
• fit

Warning Signs

The helmet should be removed from use temporarily when there are:

• cracks or breaks in the outer shell
• significant deformation
• damaged mounting points
• missing interior components
• leaking air liners
• severely compressed padding
• a broken or severely bent facemask
• missing or damaged hardware
• an unstable fit despite correct adjustment

Detailed information can be found under Football Helmet Lifespan, Inspection and Replacement.

Modifications, Attachments and Non-Original Components

Do Not Drill or Modify the Helmet Independently

Additional holes, cut shell areas, heated plastics or glued cracks may alter the helmet’s construction.

Even with apparently minor modifications, consider that:

• forces may be distributed differently
• mounting points may be weakened
• components may no longer function as intended
• manufacturer or league requirements may be violated
• the certification status may be affected

Use Only Compatible Facemasks and Hardware

Speed, SpeedFlex, F7, F7 AiR, Vengeance and LIGHT systems use different facemasks, clips and mounting components.

A facemask that looks similar must not be installed solely because of its shape or size.

Additional Helmet Covers and Attachments

External helmet covers or additional impact-absorbing attachments may be used in certain training or game environments. However, their compatibility and permitted use depend on the specific product, helmet model, manufacturer and competition rules.

Before use, check:

• is the product specifically compatible with the helmet model?
• does the helmet manufacturer permit its use?
• is the attachment allowed during training or games?
• does it alter the function of the facemask or chinstrap?
• does it restrict vision or freedom of movement?

Eyeshields and Visors

Eyeshields must also be compatible with the facemask and the intended mounting hardware. Clear, tinted or mirrored versions may be regulated differently depending on the league.

What Should You Do If a Concussion Is Suspected?

A suspected concussion is primarily a medical issue, not an equipment issue.

Remove the Player from Play Immediately

If a player shows possible symptoms following a blow to the head or body, the player should be removed from training or the game immediately.

Possible signs may include:

• headache
• dizziness
• nausea
• balance problems
• confusion
• memory loss
• sensitivity to light or noise
• slowed reactions
• unusual behavior
• loss of consciousness

This list is not complete. Symptoms may appear immediately or after a delay.

No Return on the Same Day

When a concussion is suspected, the player should not return to training or the game on the same day.

The player should return to sport only after medical clearance and in accordance with the appropriate return-to-play procedure.

The Condition of the Helmet Does Not Rule Out an Injury

An undamaged helmet shell does not mean that no concussion has occurred. Conversely, a damaged helmet does not automatically indicate which injury the player has sustained.

Inspect the Equipment Afterwards

Regardless of the medical assessment, the helmet should be inspected following an unusual impact for:

• cracks and deformation
• a damaged facemask
• loose or missing hardware
• changes to the interior padding
• leaking liners
• changes in fit

What Role Do Playing Rules and Technique Have?

Helmet safety involves more than purchasing a particular model.

Risk reduction also includes:

• proper tackling and blocking technique
• avoiding intentional head contact
• enforcement of the rules
• medical support
• recognizing and reporting symptoms
• limited and appropriately planned contact exposure
• regular equipment inspections
• correct fitting by players, parents and coaches

The Head Should Not Be the First Point of Contact

Players should not enter contact with the head lowered and the crown leading. A modern helmet design does not make dangerous technique safe.

Symptoms Must Be Reported

Players should not hide headaches, dizziness, vision problems or other unusual symptoms in order to continue playing.

Common Misconceptions about Football Helmets

“A Five-Star Helmet Prevents Concussions.”

No. A five-star rating describes performance within the relevant Virginia Tech test method. It is not a guarantee against injury.

“The Most Expensive Helmet Is Automatically the Safest.”

No. Prices, features and adjustment options may differ. An expensive helmet with an unsuitable fit is not a good choice.

“A NOCSAE Mark Means the Helmet Never Needs to Be Replaced.”

No. Damage, wear, incompatible components, unauthorized modifications and missing recertification may prevent further use.

“A Helmet without a Visible Crack Is Always Fine.”

No. Leaking liners, damaged mounting points, compressed padding or an unstable fit may also be problematic.

“An Oversized Helmet Can Simply Be Inflated More.”

No. Air liners are intended for fine adjustment. They cannot reliably correct an incorrect basic size.

“Youth and Varsity Ratings Can Be Compared Directly.”

No. The test methods differ. Results from different categories must not be compared directly.

“A New Helmet Replaces Safe Tackling Technique.”

No. Proper technique and avoiding intentional head contact remain essential.

FAQ – Football Helmet Safety

Selecting and Using a Football Helmet Safely

Football helmet safety cannot be reduced to a brand, price or individual star rating. The helmet model must be certified or otherwise suitable for the intended level of play, fit the player’s head shape, be adjusted correctly and be inspected regularly.

All currently available helmets, facemasks and accessories can be found under American Football Helmets & Facemasks.
