IJsselpool

What IJsselpool does

IJsselpool is a cooperative teacher replacement pool (vervangingspool) operating in the Netherlands as a shared-service organization for five affiliated primary school boards: Stichting Archipel, Stichting IJsselgraaf, Stichting ProCon, Stichting PCBO Voorst, and SKBG onderwijs. Collectively these boards operate 63 primary schools across 11 municipalities in the Achterhoek and Veluwe regions. IJsselpool's core function is to coordinate substitute teachers and teaching assistants when regular staff are absent due to illness or other reasons, offering five engagement models: a fixed pool (Vaste Pool), a flex pool (Flex Pool), an OAS-pool for teaching assistants, a 2e Lijst (on-call substitutes), and a Leerkrachtenpool for part-time teachers seeking extra hours. Substitutes are formally employed by one of the five school boards under the CAO Primair Onderwijs collective labor agreement, and IJsselpool itself has no independent legal entity — the school boards hold legal responsibility for personal data processed.

The operational backbone is VervangingsManager, a proprietary web application used for absence registration and replacement planning, managed by multiple planners and a coordinator. The organization employs only 7 staff, reflecting a lean, locally concentrated model rather than a scalable technology platform. Schools served span diverse educational approaches including Montessori, Jenaplan, Dalton, EarlyBird, gifted education, talent development, Snappet, The Leader in Me, and special primary education, which IJsselpool markets as a varied work environment for substitutes. Go-to-market is effectively direct sales to the five founding boards, with candidate recruitment conducted through the organizational website (ijsselpool.nl), email outreach, downloadable guides (Wegwijzer), and listings on partner school board websites. The entire revenue model is service-based: substitute salaries flow through the participating school boards under CAO-defined rates, and IJsselpool operates as the coordination and dispatch layer between absent teachers and available substitutes.

Emerging players

• SubstituteAlert: US-based substitute placement notification platform for K-12 districts. Comparable as a digital substitute-dispatch tool, though a much smaller and more US-centric competitor than the Frontline/PowerSchool incumbents.

Direct peers

• SmartFindExpress (PowerSchool): Substitute teacher absence-management platform now part of PowerSchool's K-12 suite. Directly comparable technology peer to VervangingsManager, enabling automated dispatch of substitutes across school districts.
• Frontline Education: US-based K-12 substitute management and absence-management SaaS provider (formerly Aesop). Directly comparable to VervangingsManager as the technology backbone for organizing teacher replacements across school districts.
• Stichting Vervangingspool PO Noord: Regional Dutch teacher-replacement pool serving primary-education school boards in the northern Netherlands. Closest structural analogue to IJsselpool — same cooperative substitution model, same CAO Primair Onderwijs employment terms, different geographic footprint.

Regional players

• Onderwijs in Dienst (OiD): Dutch organization providing HR and substitute-staffing services to primary-education school boards. Comparable as a substitute-pool and HR-administration channel, but typically structured as a sectoral service rather than a single-region cooperative.

Broad incumbents

• Tempo-Team Onderwijs: Dutch staffing brand within Randstad Group focused on education, healthcare, and government. Comparable substitute-teacher placement offering for school boards, but operating at national scale rather than a single regional cluster.
• Randstad Nederland Onderwijs: Large Dutch staffing firm with a dedicated education vertical that supplies substitute teachers and support staff to school boards nationally. Comparable as an outsourced substitute-staffing channel for primary education, but serves a far broader market and lacks IJsselpool's regional depth.

Others

• Vervangingsfonds / Participatiefonds: Dutch sectoral funds administered by werkgevers in primair onderwijs that finance sick-leave replacement costs. Indirectly comparable as a structural component of the substitute-teacher financing chain in which IJsselpool's pools operate.
