What is CTDL?
CTDL is a web application for NAATI CT exam preparation in the English-to-Chinese direction. It combines a bank of exam-style source texts, AI grading modelled on the published Certified Translator assessment rubric, and a review system that remembers your past mistakes.
Each graded attempt produces a band score per dimension, an itemised error list and a reference translation with sentence-level analysis. Over time CTDL groups your errors into weak points and plots your bands and pass rate, so you can see whether you are actually closing the gap.
Everything one practice session needs
From the source text to the review card, each step is designed around how the CT exam is assessed.
Exam-style Task A and Task B
Translate a roughly 250-word non-specialised text with its Translation Brief, or revise a flawed translation by marking, categorising and correcting each error.Rubric-based band scoring
AI grading scores every dimension on the 1–5 band scale, flags each error as major or minor, and shows where you sit against the pass line.Question any verdict
Ask follow-up questions about a score or a flagged error. If your argument holds, the dimension can be re-graded and the decision is recorded.Deep learning per text
Compare your version with a reference translation, break down long sentences step by step, and collect vocabulary and expressions worth keeping.Weak points that update themselves
Recurring errors are detected and grouped into weak-point categories with priority and recurrence, and marked resolved once they stop appearing.Progress you can measure
Track band trends per dimension and your pass rate by day, week or month, with a weekly AI commentary on what changed.
