A feeder series is distinguished from a standalone championship by its explicit function: it exists to develop drivers — and sometimes engineers and team personnel — for a higher-tier series. Entry criteria, car specifications, cost structures, and prize arrangements are designed to produce graduates who are competitive at the next level. The FIA's Superlicence points table formalises this for open-wheel racing, assigning points to each series so that only drivers who have demonstrated consistent front-running competence can qualify for an F1 seat. Series that carry more superlicence points are by definition closer to the top of the ladder.
The FIA's single-seater Global Pathway runs from karting through four main steps:
[[fia-formula-4|Formula 4]] national championships (British F4, Italian F4, ADAC F4, and others) are the entry-level rung above karting. Standardised around affordable spec chassis and engines, they are the first step where superlicence points are awarded.
[[formula-regional|Formula Regional]] championships (Formula Regional European Championship, Formula Regional Asian Championship) sit above F4, providing additional grid density and European circuit exposure before the FIA global championships.
[[fia-formula-3|FIA Formula 3 Championship]] is a global series running as a support event at European grands prix. It uses Dallara F3/20 chassis with Mecachrome engines and awards 12 superlicence points to the champion.
[[fia-formula-2|FIA Formula 2 Championship]] is the final step — the successor to GP2, rebranded in 2017. The fully spec series (Dallara F2/18, Mecachrome, Pirelli) awards 40 superlicence points to the champion, meeting the 40-point threshold for an F1 superlicence in a single season. Recent graduates who moved directly to F1 include Charles Leclerc (2017 champion), George Russell (2018), Oscar Piastri (2021), and Gabriel Bortoleto (2024). Lando Norris, 2025 F1 World Champion, is the first F2 graduate to win the F1 title.
The feeder concept extends beyond open-wheel racing. In endurance racing, [[lmp3|LMP3]] feeds into [[lmp2|LMP2]] which feeds into the [[fia-world-endurance-championship|WEC]] Hypercar class. In GT racing, GT4 feeds GT3 which accesses [[gt-world-challenge|GT World Challenge]] and ultimately factory manufacturer programmes. In North American motorsport, [[indy-nxt|Indy NXT]] (formerly Indy Lights) is the formal feeder to [[indycar|IndyCar]]. The [[asian-le-mans-series|Asian Le Mans Series]] functions as a feeder to the 24 Hours of Le Mans through its champion invitation policy.
The feeder system became increasingly formalised in the 2020s through the FIA's explicit superlicence points weighting. Cost caps and spec-series rules lowered barriers for talent from smaller markets. The collapse of the [[w-series|W Series]] in 2022 — a dedicated women's single-seater development series — highlighted the fragility of developmental series that lack manufacturer or commercial backing, demonstrating that structural integration into the mainstream ladder is more durable than standalone series positioned outside it.
[[fia-formula-2|FIA Formula 2 Championship]] — the direct F1 antechamber, final ladder step
[[fia-formula-3|FIA Formula 3 Championship]] — the step below F2 on the global ladder
[[formula-one|Formula One]] — the pinnacle the open-wheel ladder feeds into
[[indy-nxt|Indy NXT]] — the IndyCar feeder series equivalent in North America
[[asian-le-mans-series|Asian Le Mans Series]] — endurance racing feeder via Le Mans champion invitations
[[lmp3|LMP3]] — the endurance racing equivalent entry rung
