Baseline testing is one of the most effective tools we have to ensure safe concussion recovery and return-to-play decisions. Yet, it’s also one of the most misunderstood.
Many assume that a baseline test is a single computer-based quiz done in 10 minutes. But true concussion baseline testing is a multi-domain, pre-season evaluation of the brain and body — designed to create an objective reference point for post-injury care.
This guide explains what baseline testing is (and isn’t), what should be included in a proper test, and how it supports both safer recovery and better long-term outcomes.
FYI: For a more in-depth, detailed review of baseline testing, see our COMPLETE Guide to Concussion Baseline Testing.
🧠 What Is Concussion Baseline Testing?
Baseline testing involves a comprehensive assessment of brain function before an injury happens. The idea is simple: if an athlete gets a concussion later in the season, clinicians can compare their post-injury performance to their own pre-injury data.
According to the Complete Concussions training curriculum, a proper baseline test assesses multiple neurological domains that are commonly affected by concussion, including:
- Reaction time (hand-based and digital)
- Processing speed
- Attention and memory
- Balance and postural stability
- Visual tracking and oculomotor control
- Vestibular function
This provides a clear and personalized reference point, helping guide return-to-learn, return-to-work, and return-to-play decisions.
❌ What Baseline Testing Is NOT
Baseline testing is not a diagnostic tool. It doesn’t prevent concussions, nor should it be used alone to determine whether someone is cleared.
It’s also not just a computerized cognitive test. Numerous independent studies have shown that tools like ImPACT™ or SCAT, while helpful in initial screening, do not evaluate all the neurological systems affected by concussion — such as the vestibular, oculomotor, and cervical components — and therefore should not be used in isolation for return-to-play decisions (2).
Instead, baseline testing should be seen as a vital part of a full concussion management plan.
🧪 Why Baseline Testing Matters
Without baseline data, clinicians have to rely on normative averages or symptom reports to make return-to-play decisions. But studies show that:
- Athletes underreport symptoms to return faster (especially adolescents)
- Post-injury testing can appear “normal” even when recovery isn’t complete
A 2022 study by Haider et al. showed that using individualized baseline data reduced misclassification and premature RTP clearance by over 20% (1).
When baseline data is available, providers can objectively compare an athlete’s post-injury status to their own functional norm — not just “average” population scores.
🩺 What Should Be Included in a Baseline Test?
Based on Complete Concussions training and clinical protocols, a comprehensive baseline assessment includes:
- Cognitive tests (verbal memory, visual memory, reaction time, processing speed)
- Balance assessment (BESS or Sway)
- Reaction time (hand-slap test) and delayed motor response
- Visual tracking and saccades (VOMS components)
- Vestibular and oculomotor screening
- Symptom inventory
These tests take about 30–40 minutes and must be administered by a trained provider — not self-administered or done unsupervised.

🧭 When Should Athletes Be Tested?
Baseline tests should be completed annually, ideally in pre-season.
Children and teens (under 18) should be tested every 6–12 months due to rapid neurological development. Adults may retest annually or after any significant neurological change.
⚽ Who Needs Baseline Testing?
- Athletes in contact and collision sports
- School-aged children and teens
- Adults in high-risk occupations or recreational activities (e.g., skiing, motocross, rugby)
While everyone can benefit, athletes without baseline testing often face longer recovery times due to more conservative RTP protocols and lack of objective data.
