Long-term care needs assessment is the link between financing and benefits of long-term care insurance, which directly determines the benefits and has an important impact on the financing of long-term care insurance. Now there are great differences in the design of long-term care needs assessment system in pilot areas in China. Though different experiences have been gained, regional segmentation is not conducive to social equity and social mobility. Based on the social insurance attributes of long-term care insurance, combined with social reality and local pilot, and drawing appropriate lessons from Germany, an overall long-term care needs assessment system should be designed. Through a normative form of "law + administrative regulations + departmental regulations", the assessment objects should be accurately positioned, the independent assessment subjects should be assigned, the assessment indicators and tools should be scientific designed, and the assessment procedures should be strictly specified, to ensure that the evaluation results are scientific, objective and fair. And benefits should be granted according to the classification of assessment results to realize the accurate flow of long-term care insurance resources.
