In France, many organisations offer FLE classes (FLE stands for « Français langue étrangère » – French as a foreign language).
Alliances françaises, private and public language schools, linguistic training companies, university centers, higher education establishments… offer certifying trainings at different prices. For more information, go to the online map of FLE classes in France or in Paris region (both websites in French only).
Locally, some universities and associations also offer free or low-cost French classes at different levels. For more information, go to your city’s mairie (city hall).
