FIFA Natural Turf Performance Standards: A New Era for Objective Pitch Assessment in the English Football League
The introduction of mandatory FIFA Natural Turf Performance Standards (NPS) testing across the English Football League marks a significant milestone in the continued professionalisation of pitch management. From the Championship through to League Two, clubs are now required to undertake standardised pitch testing at the start of each season, providing an objective assessment of key performance characteristics across both natural and hybrid playing surfaces.
While testing and certification have long been established within the artificial turf sector, the development of the FIFA NPS framework represents one of the first attempts to create a globally consistent method of assessing natural turf performance. Importantly, the emphasis should not be viewed as a pass-or-fail exercise, but rather as a valuable benchmarking and development tool for clubs, leagues and grounds teams alike. OBI are working extensively with its partner Grounds Teams to help these reports be interpreted constructively within their clubs. Without this, such reports can and in cases are becoming weapons. Please do not hesitate to contact OBI if you require support and more context.
Why Measure Pitch Performance?
For many years, pitch quality assessments have relied heavily on visual inspections, subjective observations and anecdotal feedback from players, coaches and match officials. Whilst these perspectives remain important and in many cases more valuable than objective measures, but for league oversight they often lack consistency and can be influenced by factors entirely separate from surface characteristics.
The FIFA NPS programme introduces objective measurements that allow clubs to evaluate how a pitch performs against a standardised set of criteria. Characteristics such as firmness, traction, infiltration rate, surface density and shock absorption can now be measured consistently across different stadiums and geographical locations.
Perhaps the greatest strength of the FIFA NPS framework is that it enables objective discussions around pitch performance using measured data rather than opinion.
For leagues and governing bodies, this creates the opportunity to monitor infrastructure standards across competitions. For clubs, it provides a mechanism to benchmark performance annually and to identify areas where investment, maintenance practices or surface renovation programmes may be beneficial.
The Benefits for Clubs
Whilst the testing requirement has been introduced by the EFL, the practical benefits arguably sit primarily with the clubs themselves.
The collection of consistent performance data enables grounds teams to:
• Benchmark surfaces against league-wide averages.
• Justify investment in pitch renovation or infrastructure upgrades.
• Monitor seasonal changes in performance.
• Assess the impact of maintenance practices.
• Develop evidence-based pitch management strategies.
• Support communication with senior management and ownership groups.
The ability to present objective data provides grounds managers with a powerful tool when discussing budgets, staffing requirements and longer-term facility development plans.
Furthermore, over time, the accumulation of data will help clubs better understand how their pitches respond to weather patterns, usage intensity and renovation techniques.
Understanding the Limitations
As with any emerging performance framework, it is important that results are interpreted carefully and within the context of the individual facility.
The FIFA NPS system is still evolving and represents a significant development process for the industry. Whilst standardised testing creates consistency, it does not always account for every factor influencing a professional football pitch.
For example, infiltration rate is often largely determined by the construction profile and drainage technology installed beneath the surface.
A modern hybrid pitch built upon a high-performance sand-based profile will naturally exhibit different infiltration characteristics to an older soil-based construction.
Infiltration results should therefore be viewed as an indication of surface capability rather than a direct reflection of groundsmanship standards.
Similarly, stadium design can significantly influence turf quality. Shade, air movement, roof structures, pitch orientation and local climatic conditions can all affect surface performance but are not always factored directly into numerical scoring systems.
As a result, comparisons between clubs should be undertaken cautiously and always with consideration for the unique operating conditions of each venue.
Data Must Support Improvement, Not Criticism
One potential concern surrounding any performance testing programme is the possibility of data being misunderstood or used without sufficient context.
The purpose of testing should never be to rank or criticise grounds teams based solely on numerical outputs. Instead, the data should act as a starting point for constructive discussions around surface performance and continuous improvement.
Groundstaff are often managing challenges beyond their direct control, including ageing infrastructure, budget limitations, stadium constraints and fixture congestion.
The true value of testing lies not in assigning blame but in creating meaningful opportunities for informed decision-making.
When used appropriately, performance data becomes a powerful asset that helps support both operational and strategic planning.
Performance Characteristics Overview
The following graphs present the results recorded by OBI Sports, in collaboration with IBV, across 23 stadium pitches tested as part of the EFL programme. Each marker represents the average result for an individual stadium. Venues are deliberately not identified, in keeping with the principle that the data should inform rather than rank.
Results are plotted against colour-coded performance bands, from Excellent through to Low. Shock absorption, vertical deformation and infiltration rate are shown against FIFA reference ranges, whilst surface hardness, traction and NDVI are shown against OBI Sports’ existing benchmarking scales that are more aligned to UK pitch conditions.
Firmness: An Evolving Conversation
One of the more widely discussed areas of the FIFA NPS framework relates to surface firmness (clegg hammer) and Shock Absorptance (AAA).
The current FIFA NPS target ranges have been aligned closely with existing FIFA Quality Certification ranges. Most certified independent testing highlighted that many well-performing/highly regarded hybrid pitches comfortably operate at firmer thresholds whilst still delivering excellent playability and player acceptance.
This does not necessarily indicate a poor pitch but does reduce overall pitch rating score.
Firmness data should therefore be interpreted as part of a broader performance picture rather than in isolation.
Surface Firmness - Key Observation: No surface was recorded as too soft, and 20 of the 23 stadiums with a hardness result fell within the Excellent, Good or Average bands. Results were weighted towards the firmer side in line with preferences many grounds staff communicate, with 17 venues recording between 85 and 105. This mirrors the wider conversation around firmness set out earlier in this article with ranges requiring further discussion.
Shock Absorption / AAA - Key Observation: With the firmness readings being at the higher end of the optimum scale, it wasn’t a surprise that Shock Absorption results scored at the lower end of its optimum scale. This is a norm for hybrid pitches as a whole and with non-hybrid pitches maintaining a firmer surface especially in the early part of the season whilst full root development takes place. This does not necessarily indicate a poor pitch; rather, it reinforces that well-managed natural and hybrid pitches can operate firmer than historically developed ranges suggest.
Surface Deformation / AAA - Key Observation: Seventeen of the 23 stadiums fell within the 4–11 mm reference band, with the remaining six recording between approximately 3 and 4 mm. No results exceeded undesirable ranges.
Traction - Key Observation: Traction values showed a high degree of consistency throughout the dataset, ranging from approximately 37 to 49 Nm. Every stadium fell within the Excellent or Good bands, with 18 of the 23 rated Excellent, reinforcing the quality of surface preparation across participating venues. This was also achieved regardless of the pitch system present, not something that will be replicated in winter.
Infiltration Rate - Key Observation: Every stadium exceeded 50 mm/hr, 19 of the 23 achieved more than 100 mm/hr, and 14 sat within the Excellent band above 150 mm/hr. The wide spread of results, from just over 50 mm/hr to more than 900 mm/hr, reflects the influence of differing pitch constructions and drainage technologies, highlighting the importance of interpreting results within the context of the installed system.
Surface Density (NDVI / Turf Density) - Key Observation: NDVI data was extremely positive. Every stadium fell within the Excellent or Good bands, with the vast majority rated Excellent, indicating strong levels of turf coverage and plant vigour across pitches tested. This is a credit to the grounds teams.
A Positive Reflection on EFL Grounds Departments
Perhaps the most encouraging outcome from the initial rounds of FIFA NPS testing is the picture it paints of professional grounds management across the EFL.
Despite differences in stadium design, budgets, pitch construction methods and environmental conditions, the data has generally demonstrated a strong degree of consistency throughout the professional game.
The overall findings reinforce what many within the industry already know: the standard of groundskeeping across English professional football remains exceptionally high.
Whilst the FIFA NPS framework will undoubtedly continue to evolve, its introduction represents a positive step towards greater understanding of pitch performance. When used correctly, the data provides clubs, leagues and grounds teams with valuable insights that support informed decision-making, encourage continuous improvement and ultimately contribute to the delivery of high-quality playing surfaces.
The key message is simple: testing should not be viewed as a judgement of grounds staff, but as a tool to help the industry better understand, benchmark and continually enhance the pitches upon which the game is played.
OBI looks forward to hearing from and working alongside more grounds teams as they join the most widely used testing system in the UK!
