Ratios back in focus as international data prompts questions about staffing, safety and quality
New international data has renewed debate about educator-to-child ratios, workforce pressures, child safety and whether current staffing models remain fit for purpose in early childhood education and care.
Educator-to-child ratios have long been one of the most closely watched measures of quality and safety in early childhood education and care (ECEC), but growing workforce pressure, child safety concerns and increasing complexity in childrenâs needs are prompting renewed discussion about whether minimum staffing requirements remain enough to support contemporary practice.

Ce projet de loi, portĂ© par Caroline Yadan, prĂ©tend lutter contre de nouvelles formes d'antisĂ©mitisme. Cependant, lorsque l'on lit l'exposĂ© des motifs, on remarque un amalgame entre l'antisĂ©mitisme et la critique d'IsraĂ«l (antisionisme). On peut lire par exemple : "Cette haine de lâĂtat dâIsraĂ«l est aujourdâhui consubstantielle Ă la haine des Juifs. Lâappel Ă la destruction de cet Ătat, parce quâil forme un collectif de citoyens juifs, est une maniĂšre dĂ©tournĂ©e de sâattaquer Ă la communautĂ© juive dans son ensemble." Cet amalgame opĂ©rĂ© par Caroline Yadan n'est pas innocent. En effet, en 2025, un tribunal correctionnel a relaxĂ© une personne accusĂ©e dâantisĂ©mitisme pour avoir soutenu la cause palestinienne. Ce mĂȘme tribunal a Ă©noncĂ© : âLa rĂ©fĂ©rence Ă IsraĂ«l ou au sionisme, dĂ©fini comme un mouvement politique et religieux visant Ă lâĂ©tablissement puis Ă la consolidation dâun Ătat juif en Palestine, ne peut, Ă elle seule, ĂȘtre interprĂ©tĂ©e comme visant la communautĂ© juive dans son ensembleâ. On peut donc craindre que ce projet de loi ne cherche Ă contrer ces relaxes et Ă obliger les juges Ă opĂ©rer cet amalgame entre antisĂ©mitisme et antisionisme afin de faire taire toute critique contre IsraĂ«l. Cet amalgame est scandaleux pour trois raisons : - Il reprĂ©sente un rĂ©el danger pour la libertĂ© dâexpression, en muselant tout soutien Ă la cause palestinienne. Si ce projet de loi devait ĂȘtre votĂ©, des slogans pacifistes comme « l'Ă©galitĂ© et la libertĂ© pour tous de la mer au Jourdain » pourraient faire lâobjet de condamnations judiciaires. Le travail des journalistes et des chercheur.e.s pourrait Ă©galement sâen retrouver censurĂ©. - Il appuie indirectement la colonisation de la Palestine par IsraĂ«l, illĂ©gale au regard du droit international. - Il dessert la lutte contre lâantisĂ©mitisme en assimilant les Juives et les Juifs Ă la politique de Benjamin Netanyahou alors que nombre dâentre elleux critiquent ouvertement (et Ă juste titre) cette politique mortifĂšre. Oui, il faut lutter contre l'antisĂ©mitisme de toutes nos forces, comme contre toutes les autres discriminations. Mais pas en muselant la libertĂ© d'expression ni en assimilant la communautĂ© juive Ă la politique de Benjamin Netanyahou. Oui, IsraĂ«l est un Ă©tat qui a orchestrĂ© des expulsions (comme durant la Nakba de 1947-1948), expulsions encore perpĂ©trĂ©es en 2025 en Cisjordanie contre des camps de rĂ©fugiĂ©.e.s. Oui, la rĂ©sistance palestinienne contre l'occupant israĂ©lien par tous les moyens nĂ©cessaires est un droit garanti par la rĂ©solution des Nations Unies 2621 XXV du 12 dĂ©cembre 1970. DĂ©putĂ©.e.s, je vous appelle Ă voter contre ce projet de loi liberticide appuyant une politique colonialiste et gĂ©nocidaire contre les Palestinien.ne.s.

A long time ago I thought was a good Idea to get a simple DJ mixer to control that very simple sound source. Of course I changed my mind after a while, because I missed my full control that I have on my fully featured mixing consoles.
Because there is no way to control {compress} the signal coming in from a microphone, I had to speak very carefully because my voice can reach enormously high levels of decibels which would of course distort at the diaphragm.
Note
Peavy makes sturdy PA audio equipment. Their B class amps were so robust, you would need to pour liquid into them before you could blow their end stages
