Subclaims¶

q2 i? Across prompting configurations, content-oriented traits (Content, Prompt Adherence, Language, Narrativity) consistently achieve substantially higher QWK alignment than form-oriented traits (Organization, Word Choice, Sentence Fluency, Conventions). → Heejin Do 2026 q2 i? Even the best proprietary prompting configuration reaches only 0.695 average QWK on content-oriented traits versus 0.458 on form-oriented traits, with Conventions weakest under every prompting setting. → Heejin Do 2026

q2 · i? · causal · r2

Automated evaluation of eight prompting configurations for two proprietary LLMs on ASAP/ASAP++, scoring generated essays with a frozen multi-trait AES verifier and reporting QWK. The text reports Claude's best configuration reaching "only 0.458 on form-oriented traits" and that "Conventions remains the weakest trait under every prompting setting."

"on content-oriented traits but only 0.458 on form-oriented traits. Likewise,Conventions remains the weakest trait under every prompting setting."

• Data scarcity and long-form generation remain bottlenecks: on Prompt 8 prompting outperforms SFT and GRPO — related
• In one essay-feedback system, fine-tuned models produced no usable deep-level feedback output, so only directly prompted LLMs were evaluated; the authors suggest prompting may be more effective than supervised fine-tuning for this task — related
