[¶ 1] C.S. appeals from a juvenile court’s order adjudicating his child, T.S., a delinquent and unruly child for committing disorderly conduct. C.S. argues insufficient evidence exists to support the juvenile court’s findings of fact and asserts the juvenile court violated T.S.’s constitutional rights by failing to sua sponte conduct a competency hearing. We affirm.

[¶2] On June 1, 2010, the State petitioned the juvenile court to find T.S. is a delinquent child. The State asserted T.S. had committed two separate acts of disorderly conduct in violation of N.D.C.C. § 12.1-31-01(1). On July 1, 2010, the State amended its petition, alleging T.S. is also an unruly child under N.D.C.C. § 27-20-02(19)(b) in need of treatment and rehabilitation.
[¶ 4] The second act of disorderly conduct took place on a school bus. The bus driver testified that while driving the special needs bus on May 6, 2010, she heard T.S. scream “[b]ang, bang, T’s dead,” referring to another student on the bus. T.S. then started screaming the “N” word. The bus driver stopped the bus and attempted to calm T.S. down. She asked T.S. to go to the front of the bus, but he refused and called her “asshole” and “fat ass.” The bus driver used physical force to restrain T.S.
[¶ 5] The juvenile court issued its findings of fact and order of disposition on August 30, 2010. The juvenile court found T.S. was a delinquent and unruly child. The court, however, deferred disposition to allow for the appointment of counsel for C.S., T.S.’s father, during the dispositional phase of the delinquency proceedings.
[¶ 6] On September 13, 2010, the juvenile court held a dispositional hearing. At the hearing, the State called as its witnesses T.S.’s new school principal, a number of psychologists, T.S.’s social worker, and T.S.’s guardian ad litem. The testimony offered at the hearing established T.S. suffers from an oppositional defiance disorder and depression and that the best treatment option for T.S. is a placement outside the home.
[¶ 7] On September 17, 2010, the juvenile court issued its findings of fact and order of disposition. The juvenile court found T.S. is a delinquent child and an unruly child in need of treatment and rehabilitation. The court concluded it is in the best interest of T.S. to be removed from the care of his father and be placed in the care, custody, and control of Stuts-man County Social Services for a period of one year. C.S. subsequently requested the juvenile court change the duration of the placement from one year to a period not to exceed twelve months. The juvenile court granted the request.

[¶ 8] Under N.D.R.Civ.P. 52(a), we review a juvenile court’s factual findings under a clearly erroneous standard of review, with due regard given to the opportunity of the juvenile court to judge the credibility of the witnesses. “A finding of fact is clearly erroneous if there is no evidence to support it, if the reviewing court is left with a definite and firm conviction that a mistake has been made, or if the finding was induced by an erroneous view of the law.” Interest of A.R.,
[¶ 9] C.S. argues insufficient evidence exists to support the juvenile court’s finding T.S. is a delinquent and unruly-child.
[¶ 10] “A conviction rests upon insufficient evidence when, even after viewing the evidence in the light most favorable to the prosecution and giving the prosecution the benefit of all inferences reasonably to be drawn in its favor, no rational factfinder could have found the defendant guilty beyond a reasonable doubt.” Interest of L.B.B.,
[¶ 11] The State petitioned the juvenile court to find T.S. is a delinquent and an unruly child, alleging T.S. committed two separate acts of disorderly conduct in violation of N.D.C.C. § 12.1-31-01(l)(a), (b), and (g). Section 12.1-31-01(1), N.D.C.C., provides:
An individual is guilty of a class B misdemeanor if, with intent to harass, annoy, or alarm another person or in reckless disregard of the fact that another person is harassed, annoyed, or alarmed by the individual’s behavior, the individual:
a. Engages in fighting, or in violent, tumultuous, or threatening behavior;
b. Makes unreasonable noise;
[[Image here]]
g. Creates a hazardous, physically offensive, or seriously alarming condition by any act that serves no legitimate purpose ...
[¶ 12] C.S. argues the juvenile court clearly erred in finding T.S. is a delinquent and unruly child for having committed the two acts of disorderly conduct alleged by the State in its petition because T.S. did not have the requisite intent to commit the offenses. Noting T.S. was seven years and eight months old at the time of the acts, C.S. urges us to extend the statutory presumption of incapacity for children under the age of seven to T.S. See N.D.C.C. § 12.1-04-01 (“Persons under the age of seven years are deemed incapable of commission of an offense defined by the constitution or the statutes of this state.”). Our case law and criminal statutes, however, provide otherwise.
[¶ 13] We have long stated the legislature has the power to determine the age of criminal responsibility. See Interest of M.C.H.,
[¶ 14] Further, the record shows T.S. had the requisite intent. We have stated that, often, the only method of proving criminal intent is through circumstantial evidence. State v. Olson,

[¶ 15] C.S. argues the juvenile court violated T.S.’s due process rights by failing to sua sponte order a competency hearing to determine whether T.S. was competent to proceed with the adjudicative stage of the delinquency proceedings.
[¶ 16] The due process right of a juvenile to be determined competent as a prerequisite to the adjudicative stage of a delinquency proceeding is an issue of first impression in North Dakota. Thus, we must first determine whether due process demands a juvenile be afforded the right to a competency hearing before he is subjected to the adjudicative phase of delinquency proceedings. If such a right exists, we must determine whether the juvenile court erred by failing to sua sponte order a competency hearing for T.S.

[¶ 17] The United States Supreme Court has long recognized that although juvenile proceedings are civil in nature and must not conform with all of the requirements of a criminal trial, such proceedings “must measure up to the essentials of due process and fair treatment.” Kent v. United States,
[¶ 18] Competency to stand trial is fundamental to our adversary system of justice, because upon it depend the rights encompassed in the essential requirements of due process and fair treatment, including the right to effective assistance of counsel, the right to call, confront, and cross-examine witnesses, and the right to testify on one’s behalf or to remain silent without a penalty for doing so. See Drope v. Missouri,

[¶ 19] Having held that due process demands a juvenile be afforded the right to a competency hearing before he is subjected to the adjudicative phase of delinquency proceedings, we now turn to whether the juvenile court erred by failing to sua sponte order a competency hearing for T.S.
[¶20] We review a trial court’s failure to sua sponte order a competency hearing for obvious error affecting the accused’s substantial rights. Gleeson,
[¶ 21] The test for determining an accused’s competency to stand trial is whether the accused “has sufficient present ability to consult with his lawyer with a reasonable degree of rational understanding [] and whether he has a rational as
[¶ 22] We have explained, however, that “[o]n appeal, the issue is not whether the [accused] was competent to stand trial, but rather whether the failure to hold a competency hearing constitutes a denial of due process.” Gleeson, at ¶ 9 (citing United States v. Day,
[¶ 23] We have identified four, nonexclusive factors relevant to determining whether the evidence before the trial court should reasonably have raised a doubt as to the accused’s competency: (1) the accused’s irrational behavior; (2) the accused’s demeanor before the trial court; (3) any prior medical opinions on the competency of the accused to stand trial; and (4) any questioning of the accused’s competency by counsel before the trial court.

[¶ 24] The order of the juvenile court is affirmed.
