I thought UC allowed validation of geometry through a higher-level course for which geometry is a prerequisite, but it looks like that is no longer the case:
Geometry: The omission of a yearlong geometry course cannot be validated by advanced-level math courses (e.g., Algebra II/ Trigonometry, Trigonometry, Math Analysis, Precalculus or Calculus). However, validation applies in the following cases:
• The omission of the first semester of geometry can be validated by successful completion of the second semester of geometry with a letter grade of C or better.
• The omission of a yearlong integrated course with sufficient geometry content (e.g., Math II) can be validated by a higher level integrated course (e.g., Math III) with a letter grade of C or better, provided that the higher-level course shows clear evidence of geometry content.
• The omission of the first semester of an integrated course with sufficient geometry content (e.g., Math II) can be validated by successful completion of the second semester of an integrated course with sufficient geometry content with a letter grade of C or better.
Please note: Standardized exams (SAT, ACT, SAT Subject Test, AP, IB, etc.) cannot validate the omission. However, we will accept a “challenge†examination, administered by the high school (e.g., the school geometry course final exam), to demonstrate proficiency to validate the course omission if the high school awards both grades and units for the successful completion of such an exam.
