While very few schools still want to pay us by check/cheque there are still some, usually in the USA and Canada. Banks have tried very hard to discourage their use, particularly internationally, by massively raising fees and delaying remittances. We have kept the option alive for some schools for which it was a requirement. This became much more difficult when COVID19 arrived.
Recently our bank has told us that they will no longer accept foreign currency checks/cheques. We are left with no choice but to follow their lead and have recently removed the option from our website.
Schools can now remit using credit cards, PayPal or direct deposit to our Australian bank account. In some circumstances we can also offer direct deposit to a local account (particularly in the US). This is negotiated on a case-by-case basis and there is no option to deposit checks to the local account.
In summary, we can no longer accept checks/cheques as payment.
