Other parents in the area have been more welcoming. The principal of the school in Filippiada and some parents there said the letter sent by the parents in that area did not reflect their views. In Oraiokastro, Alexandra Hapsi, 41, has two children in school. She said she had cooked food and donated clothes for refugees living at the sprawling camp at Idomeni, farther north, which was shut this year. “In Europe, no one is taking in refugees, and they call us racist,” she said, adding that she also wanted reassurances that the refugees attending local schools had been vaccinated.

Asterios Batos, whose children attend the same school as Ms. Hapsi’s, leads the group representing the parents’ associations of all 41 schools in the broader region. “This image of a racist municipality is unfair,” he said, referring to the broader region. “We’re not racists. We’re concerned about whether all the right precautions have been taken.”

The plan calls for the migrant children to attend school in the afternoons. Initially, they would be kept in classes separate from Greek children, but they would eventually be merged into the general student population. In comments to Greek television last week, the education minister, Nikos Filis, said the program for the induction of refugees into schools included vaccinations. The lessons will be in Greek, math and English, or another language, depending on where the refugees plan to travel on to.
