Fixed the case statement
SELECT id
FROM education_program
WHERE name = CASE %s
WHEN 'SENIOR HIGH SCHOOL GAS'
THEN 'General Academic Strand'
WHEN 'SENIOR HIGH SCHOOL HUMSS'
THEN 'Humanities and Social Sciences'
WHEN 'SENIOR HIGH SCHOOL STEM'
THEN 'Science, Technology, Engineering and

ELSE %s
END
AND department_id
IN (SELECT id
FROM profile_department
WHERE school_id=1)
""", [course, course])
