Definition
The degree of care is the level of caution, attention, and prudence that a person is legally required to exercise in a given situation. It is the measure against which conduct is evaluated when determining whether a party acted negligently or fulfilled a legal duty.
The required degree of care is not fixed. It varies according to the circumstances, the relationship between the parties, and the nature of the activity or risk involved. Courts and commentators have identified several recurring standards:
1. Ordinary care (reasonable care): The baseline standard in most negligence cases. The care that a reasonably prudent person would exercise under the same or similar circumstances. This is the dominant standard in modern tort law.
2. Slight care: A lower threshold, historically associated with gross negligence or bailment situations where a party derives little or no benefit. Failure to exercise even slight care amounts to gross negligence.
3. Great (or utmost) care: A heightened standard applied to common carriers, certain bailees, and others who hold special responsibility for the safety of persons or property entrusted to them.
4. Care proportional to age and capacity: Applied to children and, in some jurisdictions, persons with cognitive limitations. A child is held only to the degree of care ordinarily exercised by children of similar age, intelligence, and experience under like circumstances — not to the adult reasonable-person standard.
The degree of care required in any given situation is a legal question when the standard is established by rule or statute; it becomes a factual question for the jury when the circumstances must be weighed against the general reasonableness standard.

Common Confusion
"Degree of care" and "standard of care" are often used interchangeably, but they are not identical. The standard of care describes the legal benchmark itself — what a person must do. The degree of care describes the intensity or level of that standard — how much care is required. In practice, the distinction is largely academic in ordinary negligence cases, where both phrases reduce to the reasonable-person test. The difference becomes more significant where the law formally recognizes gradations: slight, ordinary, and great care. Researchers encountering "standard of care" in medical malpractice sources should note that term has acquired its own specialized meaning in that context, distinct from its use in general negligence doctrine.

Core Elements
Courts assessing whether the required degree of care was met generally consider:
- The magnitude of the risk: greater danger demands greater care.
- The probability of harm: how foreseeable was the injury given the circumstances.
- The burden of precaution: what a reasonably careful person could and would have done.
- The relationship between the parties: special relationships (carrier/passenger, possessor/invitee) may elevate the required degree.
- The characteristics of the actor: age, known disability, or professional status may modify the applicable standard.

Why It Matters in Research
Researchers working in historical tort materials must account for a significant doctrinal shift. Nineteenth- and early twentieth-century sources routinely employed a formal three-tier gradation — slight, ordinary, and great care — borrowed largely from civil law and bailment doctrine. Bouvier's and other period dictionaries reflect this framework. Modern common law has largely collapsed this tripartite structure into the single reasonable-person standard, treating "slight" and "great" care as markers on a single continuum rather than distinct legal categories. A case or treatise citing "great care" as an independent legal standard may be applying a rule that no longer exists in that form in most American jurisdictions.
The child-care rule noted in Bouvier's — that a child is held only to the degree of care exercised by children of similar age under similar circumstances — remains good law in most jurisdictions, but its application has been refined over time. Researchers tracing the minority standard for negligence should look for the companion rule that treats child defendants differently from child plaintiffs.
Common carriers present a specific research trap: the "utmost care" or "highest degree of care" standard once applied broadly to carriers has been modified or abrogated by statute in several jurisdictions and is now a contested point in aviation and rail litigation. Do not assume historical carrier cases reflect current law without checking the jurisdiction's current statutory framework.
The phrase "degree of care" also appears in criminal law contexts — particularly in statutes defining criminal negligence and recklessness — where the required degree of departure from ordinary care triggers criminal liability rather than civil liability. Cross-referencing tort and criminal sources is necessary when researching vehicular homicide, criminal endangerment, or similar offenses.

Historical Dictionary Support
Bouvier's Law Dictionary offers a narrow illustrative entry, using the child-care rule to demonstrate the concept rather than defining it comprehensively. The Kentucky citation (150 Ky. 831) reflects early twentieth-century common law application of the child standard — useful as a period example but not representative of the full doctrinal framework. Bouvier's does not address the tripartite slight/ordinary/great structure under this heading, though that framework appears elsewhere in his entries on bailment and negligence.
The absence of a comprehensive definition in Bouvier's is itself informative: by the early twentieth century, "degree of care" was treated as a contextual modifier rather than a term requiring independent definition, with the operative content found in entries for specific relationships (bailee, carrier, innkeeper) and under negligence itself. Researchers relying solely on this entry will miss the broader doctrinal architecture.

Jurisdictional Note
A minority of states retain statutory or case-law recognition of the formal tripartite gradation (slight, ordinary, great care) in specific contexts such as bailment and gross negligence statutes. Most states have moved to a unitary reasonable-person standard with the degree of care adjusted by circumstances rather than by formal category.
