were previously subjects in their own right, were incorporated into the Chinese language subject(s), whereas Filipino (Tagalog) and Philippine history, civics and culture became newly required subjects. The changes in Chinese education initiated with the 1973 Philippine Constitution led to a large shifting of mother tongues, reflecting the assimilation of the Chinese Filipinos into general Philippine society. The older generation of Chinese Filipinos, who were educated in the old curriculum, typically use Philippine Hokkien at home, while most younger-generation Chinese Filipinos are more comfortable conversing in English, Filipino (Tagalog), and/or other Philippine languages like Cebuano, including their code-switching forms like Taglish and Bislish, which are sometimes varyingly admixed with Philippine Hokkien to make Hokaglish. Curriculum Chinese Filipino schools typically feature curriculum prescribed by the Philippine Department of Education (DepEd). The limited time spent in Chinese instruction consists largely of language arts. The three core Chinese subjects are "Chinese Grammar" (), "Chinese Composition" (), and "Chinese Mathematics" (). Other schools may add other subjects such as "Chinese Calligraphy" (). Chinese history, geography and culture are also integrated in all the three core Chinese subjects – they stood as independent subjects of their own before 1973. Many schools currently teach at least just one Chinese subject, known simply as just "Chinese" (). It also varies per school if either or both Traditional Chinese with Zhuyin (known in many schools in Hokkien ) and/or Simplified Chinese with Pinyin is taught. Currently, all Chinese class subjects are taught in Mandarin Chinese (known in many schools in Hokkien ) and in some schools, students are prohibited from speaking any other language, such as English, Filipino (Tagalog), other regional Philippine languages, or even Hokkien during Chinese classes, when decades before, there were no such restrictions. Schools and universities Many Chinese Filipino schools are sectarian, being founded by either Roman Catholic or Chinese Protestant Christian missions. These include Grace Christian College (Protestant-Baptist), Hope Christian High School (Protestant-Evangelical), Immaculate Conception Academy (Roman Catholic-Missionary Sisters of the Immaculate Conception), Jubilee Christian Academy (Protestant-Evangelical), LIGHT Christian Academy (Protestant-Evangelical), Makati Hope Academy (Protestant-Evangelical), MGC-New Life Christian Academy (Protestant-Evangelical), Saint Peter the Apostle School (Roman Catholic-Archdiocese of Manila), Saint Jude Catholic School (Roman Catholic-Society of the Divine Word), Saint Stephen's High School (Protestant-Episcopalian), Ateneo de Iloilo, Ateneo de Cebu and Xavier School (Roman Catholic-Society of Jesus). Major non-sectarian schools include Chiang Kai Shek College, Manila Patriotic School, Philippine Chen Kuang High School,
