Why is French used more often than Haitian Creole in Haiti's schools and formal settings?

Although both Haitian Creole and French are official languages of Haiti, French remains the primary language of instruction in the school system and is utilized in formal settings.12

The prevalence of French in these environments is largely due to the structure of the national education system, which is based on the French model. Because the school system retains French as the main language of instruction, there has historically been limited acceptance of written Creole, despite it being the first language of approximately 95% of the population.312

While Haitian Creole is the language of daily life for the vast majority of the population, French is spoken by about one-tenth of the people and is traditionally associated with more formal circumstances. This linguistic divide has contributed to the development of a small elite who are fluent in French, though Creole continues to be used for public functions such as church services and political meetings.1243
