Compared to the Open Court years, training on the reading curriculum districtwide is more “hit or miss,” said Maria Nichols, president of the district’s principals union. Nearly all of the district’s 12,000 elementary school teachers participated in one-week reading institutes and many completed follow-up sessions throughout the year. That’s where Open Court fell short, said Nichols, with the principals’ union. Since 2015, the campaign has been a leading voice for integrating history, science and the arts into reading curriculum. Literacy advocates hope those gains will convince leaders — as Romer did with Open Court — to stick with Amplify.
