As an employer, you can pay for your employee's tuition fee free of any taxes (no salary tax, no VAT, no profit tax). Training costs are subject to the "Werkkostenregeling" (WKR), but excluded from the "forfait". See Handboek Loonheffingen under 20.1.3 (p. 222), available here.
The tuition fee is fully deductible as cost which means less profit tax.
Showing this trust to your new employees will make them work even harder to prove to you that they learn fast and can be an awesome addition to the organisation!
